2D Regularized T-Matrix Method for Acceleration of 3D Simulations During Optimization of Rod Arrays for NZI Materials

Abstract

During the optimization by means of genetic algorithms of the three-dimensional rod arrays consisting of finite-length cylinders, commonly used in the design of high-frequency resonance scattering, three-dimensional solvers, such as the multilevel fast multipole algorithm, perform the analyses with a time bottleneck. Simulation results seem independent of longitudinal dimensions in many applications. Therefore, the exploitation of the well-conditioned solvers in two dimensions appears to be worthy, and it is aimed to cast further comparisons between the two types of solvers in this contribution.
