Abstract :
A new, closed-form analytical result for evaluating the Sommerfeld integral tail for single-layer PEC-backed substrates is included. The numerical results demonstrate the smoothness of the integrand when pole singularities are subtracted out, and hence facilitate the application of real-axis numerical integration.
