Abstract :
In this paper, we present two illustrative applications of a software package based on the Conformal Finite Difference Time Domain (CFDTD) method. The examples include objects with either a curved edge, or a curved surface, that are not easily simulated accurately using the conventional FDTD technique. We show that the CFDTD simulation results agree well with the published data.
