ANSYS HFSS is the industry standard, 3D full-wave electromagnetic field solver. HFSS is used throughout the industry to compute the electrical behavior of complex high-frequency and high-speed electronic components of arbitrary shape and user-defined material properties. With HFSS, engineers can extract parasitic parameters (S, Y, Z), visualize radiating 3D electromagnetic fields (near- and far-field) and generate Full-Wave SPICE models that link to circuit simulations.
