SEMCAD X is a software framework with a high-end graphical user interface for electromagnetics and thermal simulations based on FDTD techniques that exploit both software and hardware acceleration strategies.

SEMCAD X incorporates a rich design and analysis environment by seamlessly combining modeling, simulation, optimization and post processing setups. To date, the FDTD techniques implemented in SEMCAD X have been successfully applied to a wide variety of both academic and industrial electromagnetic problems in a wide range of areas including antenna design, radiating/guiding microwave devices, electromagnetic compatibility, optics and bioelectromagnetics.

Despite the versatility achieved with this pool of FDTD solvers, there is a growing demand for a platform that tackles each part of the problem with the most suitable method and processes the specific outputs into the overall result. A large number of the structures encountered in microwave applications, given its resonant nature, constitute a challenging test field for this approach.

 

Thus, SPEAG has developed a new state-of-the-art solver based on the Mode-Matching Technique for the simulation of passive waveguide structures. This solver has been integrated into the existing SEMCAD X framework to provide the user with a common simulation environment that will abstract the method in which the solver has been implemented.

This paper presents an overview of the enhancements achieved in the simulation of mm-wave/microwave devices through a set of benchmarks, including dual-mode filters with rectangular and elliptical cavities and components for polarization discrimination.¹ Institute for Biomedical Engineering, University of Zürich and ETH Zürich, Gloriastrasse 35, 8092 Zurich, Switzerland.
