Spectral Surface Integral Equation Method for Plasmonic Nanostructures

When design of antenna relies on results of experimental research, this makes designing hugely expensive. To solve numerically the scattering problem which rises from antenna simulations, in this work a novel technique of surface parameterization in conjunction with spectral Galerkin Boundary Integral Equation (BIE) method with analytical regularization based on singularity division technique and Fast Fourier Transforms (FFT) for numerical integration of all Galerkin coefficients simultaneously is applied for the first time to solve this class of problems.
