HFSS™ is the industry-standard simulation tool for 3D full-wave electromagnetic field simulation. HFSS provides E- and H-fields, currents, S-parameters and near and far radiated field results. Intrinsic to the success of HFSS as an engineering design tool is its automated solution process where users are only required to specify geometry, material properties and the desired output. From here HFSS will automatically generate an appropriate, efficient and accurate mesh for solving the problem using the proven finite element method. With HFSS the physics defines the mesh, not the mesh defining the physics. Engineers rely on the accuracy, capacity, and performance of HFSS to design high-speed components including on-chip embedded passives, IC packages, PCB interconnects, and high-frequency components such as antennas, RF/microwave components, and biomedical devices.

The power of HFSS comes from many Ansoft pioneered research and development innovations. These breakthroughs have made HFSS the most widely used software for solving 3D full-wave electromagnetic field simulations.
