Abstract:

This report presents 2D monostatic and bistatic RCS echo width calculations for electrically and magnetically conducting circular cylinders with and without an electromagnetically damping coat. Similar calculations for dielectric cylinders and thin dielectric strips are also given. In all cases, results are computed by our new TDFD code, transformed to the frequency domain, and overlaid with canonical calculations performed directly in the frequency domain. Agreement of 10 is achieved if the TDFD code uses at least 16 cells per wavelength. To date we have not used meshes larger than 50 x 50 cells or 125 x 25 cells, but these are not intrinsic limits.
