µWave Wizard™
µWave Wizard is a design tool using the well-known fast and accurate Mode-Matching technique. This method is particularly suitable for simulation and optimization of passive microwave systems and components, including antennas. The mode matching method (MM) and their derivatives (i.e. the fast hybrid MM/boundary contour and the MM/2D-finite-element method) is the only method capable of simultaneously offering fastest processing speed and highest accuracy.
Mician’s software developers' secret for speed is to avoid the use of time consuming 3D solvers wherever possible and to focus on applying the Mode-Matching Technique and its derivatives instead, even on structures that at first glance seem to be suited for 3D solvers only. Yet, a 3D FEM solver on element level is available within the µWave Wizard for structures with very complex geometries or with features not feasible to be implemented in MM.
In addition to its fast and powerful numerical methods, the µWave Wizard offers an appealing and ergonomic GUI that enables flexibility and openness. The consequent implementation of the latest field theoretical and mathema typical approaches is Mician's challenge for the continuous enhancements of the µWave Wizard.
Typical applications for the µWave Wizard are complex passive waveguide components and structures like waveguide and combline filters, multiplexers, couplers, tapers, horn antennas and cluster feeds, OMTs, polarizers, etc. For these kinds of components, more than 300 waveguide, combline and coaxial line elements are available in our continuously expanding element library.
In order to simulate the response of a complex passive waveguide structure, it first has to be broken down into basic building blocks such as waveguides, discontinuities and special elements. These building blocks are part of the µWave Wizard waveguide component libraries. The program then calculates the scattering parameters for each individual building block and performs multi-modal element connections to simulate the response of the entire structure. The impact of higher order mode interactions is thereby strictly taken into account. The basic building block concept eliminates the need for creating a full-up 3D model of the entire structure. The dimensions of every element are conveniently parameterized and the initial design setup is completed within minutes. This feature enables the user to go directly from analysis to optimization by simply declaring specific dimensions as variable parameters to be optimized. The optimization control window is easy to navigate and facilitates the embedding of electrical specifications into the goal function. |
