Abstract

Analytical evaluation of asymptotic part of the Green´s function, in product with piece-wise sinusoidal, entire domain, and travelling wave mode basis functions, is presented. The Sommerfeld type double integral in spectral domain is solved and reduced into a single integral in spatial domain with very short integration range. The derived results lead to develop a computational efficiency improved code, which has been found 27 times faster than the earlier validated common method of moments code.
