Integral Equation-Based Solver for the Simulation of Metasurface Designs

A full-wave simulation is conducted on metasurface designs using an integral equation-based solver. This approach offers two distinct advantages over conventional and hybrid Finite-Element Method (FEM) based solvers, namely the use of a surface-based mesh instead of a volumetric representation and excellent efficiency for large-scale structures [3]. The solver is tested against measurements, a Hybrid FEM solver, as well as theoretical models for accuracy.
