Generally, users will pick up basic skills within days. Our 3D modeler is very similar to other modelers used in the industry. The software also comes with a huge design library containing examples for everything from simple RF components to complex antenna feed networks.

Yes, you can line up and sequentially execute multiple projects in Batch Mode over night or on weekends.

Yes, thanks to COM and VBA interface, μWave Wizard can be remotely controlled from third party software such as MatLab(TM). You can also create your own VBA code for exchanging data or externally driving μWave Wizard.

Yes, several mechanical output file formats are supported such as DXF, STP, STL, IGES. You can also generate picture files as Bitmap or JPG.

Yes, μWave Wizard contains synthesis tools for waveguide filters, combline filters, lowpass filters, wavguide transitions, offset reflector antennas and feed horns.

μWave Wizard supports the concept of combining several solvers, such as 2D and 3D-FEM, Mode Matching and Spherical Wave Expansion. FEM and Mode Matching are generally used for simulating RF performance of enclosed structures such as waveguides, coax or planar assemblies while Spherical Wave Expansion is used for radiating structures. Structures such as antenna feed networks will usually be solved by a combination of all methods.

No, μWave Wizard is a full-wave RF design tool. For fast composition of complex structures we are utilizing a workspace resembling a circuit modeler but within the workspace all components are simulated and connected using highly accurate modal scattering matrices.

Mician is operating globally and the U.S. and Canada are among our largest markets. Leading satellite manufacturers and numerous U.S. government agencies are using μWave Wizard for cutting edge designs.

No, quite the opposite. Instead of overextending CPU and computer memory usage by forcing one solver to mesh and converge for the most inconvenient geometry in your circuit, μWave Wizard divides a complex circuit up into smaller subcircuits and solves each one of them with a solver best suited for that particular circuit. Then all individual solutions are combined to obtain the RF performance of the entire structure.

Yes, with the help of our Interactive Tuner you can manually vary selected dimensions of your model in real time to achieve improved RF performance.

Yes, the software has three integral optimizers to choose from: Extreme, Powell and Evolution Optimization.

No, solvers are assigned automatically, in some cases allowing user overwrite.

No, the first version of μWave Wizard was introduced in 1999. In 2006 we opened our U.S. sales and support organization in California to better serve our domestic customers.

Since version 7.0 a 64 bit architecture and 64bit operating system are supported. The full version does include this feature and there are no special add-ons or other setup files required.

In short: The method of solving Maxwell's equations.

Mode-Matching (MM) method + derivations: The electro-magnetic fields inside the structure under consideration are expanded into known, analytic solutions of Maxwell's equations for similar geometries. The boundary conditions are fulfilled using a Galerkin procedure on the element surface. In the normal case only a few of these (some 100) analytic solutions (modes) are needed for sufficient convergence of the results, so this method is very fast and has low computational requirements. Because, there are only few structures with known, analytic solutions of Maxwell's equations (e.g. rectangular + circular cavities + waveguides), this method is applicable only to certain geometries and thus lacks some geometric modeling capabilities (inclusion of screws, rounded corners, draft angles, etc.)

3D solvers (FEM and FDTD): The electro-magnetic fields are expanded with very simple, locally defined expansion functions (e.g. edge element functions in FEM, delta functions in FD). Both Maxwell's equations and the boundary conditions are fulfilled either via functional (variational) analysis (FEM) or approximation of the differential operators with finite difference operators (FD). Depending on the size (in wavelengths) and the geometric complexity of the structure you may need a lot (10^4 ... 10^6) of expansion functions to achieve sufficient convergence.

Although the systems of equations are sparse (few non-zero elements pre row/column), you'll need either a lot CPU time (iterative solvers) or lot of RAM (direct solvers) of both. The 3D solvers have the advantage to offer full geometric modeling capabilities including all features (e.g. screws, rounded corners, draft angles) which are impossible or difficult to include into the MM method.

In the µWave Wizard each element can be analyzed with its own, most advantageous method. So there's no need to analyze the whole structure at once with a 3D solver. You can mix 3D solver (FEM) elements with Mode-matching elements in the same structure. Both element types have a common multi-modal interface, so they are fully compatible and interchangeable. With the breakdown of the structure into smaller elements you even profit when all parts are analyzed using a 3D solver, since the solution of many small systems of equations is still faster than solving on single big system of equations.

According to the philosophy of µWave Wizard external CAD files are not required to setup a design. For example: a typical waveguide filter is the cascading of irises and empty waveguides of certain lengths. Those elements are part of our waveguide libraries and you simply have to add your properties to the elements which you have arranged in the schematics. The properties of an iris are the waveguide housing, the aperture and the thickness. The empty waveguide between the irises is described by a length. That is all. Therefore you can setup a filter design very easy. You do not have to setup a 3D technical drawing for your desired structure; it is the arranging of the elements from our waveguide libraries.

µWave Wizard allows importing element geometries in STL-(Stereo lithography) format. The import STL-geometry is a model of a single connected, closed surface consisting of triangles. These elements can be equipped with rectangular, circular, coaxial or polygonal (2D FEM) waveguide ports and are analyzed using the 3D Finite Element method (FEM). Although the waveguide ports and the element scale factor, rotation angle and element position can be parameterized using variables and equations, the STL-file itself cannot be parameterized because the STL does not contain any information about the construction. You can of course import STL-files created by the export function of the NTL3D-viewer, but most likely you'll want to import geometries, that are not part of our element library. So for creation of these STL-files you should use external CAD-software. The import elmenents to support STL format can be found in the Import Library.

Various types, e.g. (list not complete):

Band-pass filters:

  • inline rectangular and circular waveguide iris/metal insert/circular post filters
  • inline and cross-coupled rectangular cavity filters including inherent milling radii (both in E- and H-plane)
  • inline and cross-coupled rectangular and circular waveguide dual-mode filters
  • inline and cross-coupled combline filters (incl. draft angles for die-casting, various probe types and capacitive and inductive cross-couplings)
  • interdigital filters
  • inline and cross-coupled dielectric resonator filters
  • directional (dual-mode) filters

Low-pass filters:

  • coaxial (TEM-) lowpass filters
  • E-plane corrugated filters
  • ridged waveguide and waffle-iron filters

Band-stop filters:

  • stub-type band-stop filters

High-pass filters:

  • cut-off waveguide high-pass filters

Yes, We integrating support for reflector antennas using our spherical wave expansion (SWE) and physical optics (PO) to analyze the reflector antenna. Since this model neglects the interaction between the horn and the reflector, it'll be useful only for offset reflectors.

Yes, if the fin-line structure is either filled by air or has a dielectric filling which is homogeneous all over the fin-line cross-section. For these cases it can be treated as ridged waveguide structure.

Yes, if you want to analyze typical filters, couplers, manifold multiplexers, single horn antennas etc. which are based on the  mode matching technique elements then this will be sufficient. Even running uWave Wizard on a netbook is efficient in the case that 3D-FEM computation is not in your focus. If you want to analyze and optimize more complex 3D structures and even use 3D finite elements, it'll not be sufficient - and too slow - either. We recommend a Desktop/Laptop with state of the art CPUs and least 1 GB RAM. In case of 3D-FEM elements and in particular computation of complete projects by 3D FEM a 64bit architecture and OS is recommended.

You can analyze and optimize the "active element pattern" of slot array with the µWave Wizard. That means one element
of the slot array is excited while the others are terminated, or you include a feeding network too. Furthermore, you can also obtain the complete modal scattering matrix of the array. In general the active element pattern will be varying with slot position, except when having a very large (or infinite) array. However, the size of the slot array, which can be analyzed with the µWave Wizard, is restricted. Please refer: Are their other limitations then the size of the slot array?

Depends, how your structure looks like. Fully supported are dielectric fillings in the following cases:

  • the structure is entirely filled with the same dielectric material
  • the structure contains step discontinuities between waveguides filled with different dielectric fillings (or air), but the cross-sections are homogeneous
  • the structure is composed of dielectric resonator cavities, which can be modeled by our element library.
  • Some elements like "spresdp_x_da" from the "Dielectric Resonator" library support inhomogeneous and lossy dielectric fillings by using the 3D finite element method (FEM) .

Yes, we have an element with 3 posts in a rectangular waveguide in our element library. You can easily synthesize and optimize a band-pass filter containing these elements are irises.

Yes, if the dielectric filling is homogeneous all over the waveguide cross-section.

For an evaluation of the full version of µWave Wizard you can install the µWave Wizard on your computer. Instead of using a hardware USB dongle on our computer you can lock a license on our floating license server which is connected with a multiple floating license USB dongle. Only during the analysis and optimization is a license locked. Therefore you can build up, modify and visualize your schematics without locking a license. Locking a license requires an internet connection to our server which has a unique IP address.
