Abstract :
This paper introduces a generalization of the three-dimensional finite-difference-time-domain (FDTD) method, the three-dimensional contour FDTD (CFDTD) method, is introduced. The FDTD method represents curved media boundaries as stepped edges. Through the use of subcell modeling, the CFDTD method conformably models bodies with curved surfaces, yet retains the ability to model corners and edges. Electromagnetic scattering from single and multiple bodies is presented
