Abstract :
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 from the proposed method and theoretical value, they show good agreement.
