Author: [Your Name] Date: [Current Date] Course / Purpose: [e.g., EE 525 – Computational Electromagnetics] Abstract The HFSS (High-Frequency Structure Simulator) User Guide for version 15 serves as the definitive reference for engineers using the finite element method (FEM) to model electromagnetic fields in 3D structures. This paper reviews the guide’s structure, core simulation workflows, solver technologies, mesh refinement strategies, and practical application examples. Key insights include the transition from geometry definition to adaptive meshing, boundary condition assignment, and post-processing of S-parameters and far-field patterns. The guide remains relevant for understanding fundamental FEM simulation principles despite newer versions. 1. Introduction HFSS, developed by Ansoft (now Ansys), is an industry standard for designing antennas, RF components, high-speed interconnects, and electromagnetic interference (EMI) shielding. Version 15 (circa 2013) introduced improvements in hybrid solver regions and HPC scalability. This paper synthesizes the main technical chapters of its user guide, excluding installation or licensing details. 2. Overview of the User Guide’s Structure The HFSS v15 User Guide is organized into logical learning phases:
