Mician previews µWave Wizard version 9 at EuMW 2018

µWave Wizard’s version 9 introduces the support for inhomogeneously filled waveguide ports, like microstrip lines, multi-layered coaxial lines or dielectric coated waveguides.

This feature is accompanied by a set of pre-defined library elements, like microstrip steps, stubs, tapers, patches and coupled lines, microstrip to coaxial line, rectangular waveguide and SIW transitions, steps and tapers for multi-layered media in coaxial lines, which is steadily extended according to the user needs.

In addition, inhomogeneously filled waveguide ports are supported for the user defined modeler elements and the quasi-planar elements (stacked material layers with user-defined 2D geometry).

Also new with version 9 will be Mician’s new Filter Synthesis tool, an add-on for µWave Wizard products, which is capable of designing and optimising different kinds of narrowband microwave filters.

A wide variety of filter designs from the simplest iris filter to more complex geometries such as cross-coupled combline filters can be manipulated using this tool within one interface. A feature of this tool allows either manual or automatic tuning of its physical dimensions towards a target filter response, additionally offering the user to view the 3D geometry in parallel.

Another new feature of µWave Wizard software products is 3D mesh morphing, which keeps the topology of 3D FEM meshes constant during geometry changes - as long as possible.

In this way mesh generation noise is significantly reduced and the convergence of gradient type optimizers is greatly improved. The generic implementation supports all kinds of geometry parameters, like case and iris dimensions, probe and tuning screw depth/position/diameters, milling radii and draft angles, including parameters defined by equation variables.

This feature is also supported for parametrized µWave Wizard modeler elements and for 3D FEM simulations on circuit level. Optionally it is possible to save/read the mesh morphing data to/from disk, e.g. for interruption of optimisations and restart using other frequency or goal function settings.

As a result, via µWave Wizard’s COM interface, this feature can also speed up external optimisers with user-defined optimisation strategies.
