What is HFSS ?

HFSS - High frequency structure simulator

HFSS is an industry-standard simulation tool for 3D full-wave electromagnetic field simulation.

It is essential for the design of high-frequency and high-speed component design

Applications: On-chip embedded

passives and PCB interconnects Antennas and

RF/microwave components High-frequency IC

packages EMC/EMI Biomedical devices

DEMO Model:Lets design a 50-ohm micro-strip line.

Mode of propagation : Quasi-TEM

Calculating parameters:

Field and charge distribution:
