FEST3D – High-Performance Passive Component Simulation
FEST3D, is a high-performance electromagnetic simulation tool designed for the analysis and synthesis of passive microwave components such as filters, multiplexers, and waveguide devices. It uses advanced numerical techniques the Method of Moments (MoM) and Boundary Integral–Resonant Mode Expansion (BI-RME) to deliver full-wave accuracy with faster computation times.
The software enables automatic filter synthesis, optimization, and tolerance analysis, allowing engineers to efficiently design and fine-tune waveguide and cavity-based components. With seamless integration to CST Studio Suite, FEST3D supports a complete workflow from design to full-wave validation. It is widely used in aerospace, satellite, radar, and communication systems where precision and speed are essential.
