A legendre pseudospectral frequency-domain method for solving Maxwell's equations
A pseudospectral frequency-domain (PSFD) method with multi-domain approach and based on Legendre polynomials is developed for solving Maxwell's equations. One aim of the proposed method is to more accurately model problems in plasmonics in which electromagnetic waves interact with metallic structures at optical frequencies. Calculation of light scattering by a silver circular cylinder demonstrates that the accuracy of the obtained field strength can be as good as on the order of 10−9 of the incident field strength.
