Selecting the Right 3D EM Solver for Periodic Antenna Arrays

This article goes through the most popular electromagnetic solvers for periodic structures, describing their optimal use cases, advantages and disadvantages. As a practical example, a 4x4 mmWave cavity antenna array is simulated using a Time Domain Solver, Direct Frequency Domain Solver and Domain Decomposition Solver. The goal is to compare the available 3D solvers and find the most optimal settings for simulations of periodic structures.
