Numerical analysis of surface waves on a grounded dielectric plane using the finite difference time domain method

In this paper, the FDTD method is used to analyze the electromagnetic behavior of surface waves on a grounded dielectric plane. Dispersion characteristics, scattering from plane truncations, excitation and interference on a microstrip right angle bend are discussed. The knowledge of these fundamental properties is essential if one wishes to optimize the electrical performance of packages and interconnects with respect to surface wave crosstalk and radiation losses.
