hfss

3D Full-wave Electromagnetic Field Simulation
HFSS? is the industry-standard software for S-parameter, Full-Wave SPICE? extraction, and 3D electromagnetic field simulation of high-frequency and high-speed components. Engineers rely on the accuracy, capacity, and performance of HFSS to design on-chip embedded passives, IC packages, PCB interconnects, antennas, RF/microwave components, and biomedical devices.
