摘要
This work analyzes a new efficient numerical algorithm for evaluating the time-domain electromagnetic (EM) field and the filtering behaviour of periodic waveguides, by reducing the number of equations to solve. The scalar Helmholtz-equation is utilized in order to determine the electric and magnetic Hertzian-potentials that represent the EM field. The principle of the method is demonstrated by a simple 2D application to a multilayer dielectric stack at optical frequencies.
