Fest3D is based on the integral equation technique efficiently solved by the Method of Moments. Additionally, the Boundary Integral-Resonant Mode Expansion (BI-RME) method is employed for extracting the modal chart of complex waveguides with arbitrary cross-section. The successful combination of such methods ensures a high degree of accuracy and a reduction in the computational resources required (in terms of CPU time and memory).
New features:
Coupling matrix element added to Fest3D library: this improves the filter and multiplexer design capabilities in Fest3D.
Touchstone element added to Fest3D library: results from external tools and/or measurements can now be imported in Touchstone format.
Cache (for results reuse) has been restructured: faster now and linked to the specific project.
Argon, Helium and SF6 added as gases for Corona simulation.
