Abstract

The authors present a program developed at Arizona State University to generate automatically three-dimensional surface FDTD (finite-difference time-domain) mesh for a complex object. The program is based on an efficient ray-tracing algorithm and has been tested in various numerical simulations. The mesh generator can be used for a complex object enclosed by conducting and thin-dielectric surfaces. The high efficiency of the algorithm allows the mesh generation to be performed on a special computer. As an example, the mesh generation for a scale helicopter is shown.<>
