High-Frequency Structure Simulator (HFSS) is a 3D electromagnetic (EM) simulation tool used to design a broad range of high-frequency products such as antennas, filters, and IC packages. HFSS has advanced 3D electromagnetic field solvers based on finite elements and other integral equation methods supported by high-performance computing technology that enable engineers to perform the rapid and accurate design of high-frequency and high-speed electronic components.
Ansys HFSS uses the highly accurate finite element method (FEM), the large-scale method of moments (MoM) technique, and the ultra-large-scale asymptotic method of shooting and bouncing rays (SBR) with advanced diffraction and creeping wave physics for enhanced accuracy (SBR+). The Ansys HFSS simulation suite has the following solvers to tackle manifold EM problems involving electrically small to enormous structures:
