The body of revolution finite-difference time-domain method for dispersive media is presented which reduce a three-dimensional problem to a two-dimensional one, resulting in an efficient saving of CPU running time and memory requirement. To validate the accuracy and efficiency of the proposed method, we apply it to analyze the scattering from several dispersive bodies of revolution. Compared the result...
An unconditionally stable finite-difference time-domain (FDTD) method based on the weighted Laguerre polynomials (WLP) for solving Maxwell's equations had been proposed. In this paper, a memory efficient modification to the proposed methodology is described. In this novel modification, the divergence theorem is introduced in the WLP-FDTD method, in which Maxwell's divergence equation replaces one...
