A 2D surface integral equation-based NystrOumlm solver in which a phase extraction technique is utilized to reduce the number of surface unknowns is described. As forward scattering is the dominant mechanism for the near-ground wave propagation scenario, the associated rapidly-varying phase components of the integral equation kernel and solution unknowns are deduced and isolated in advance and subsequently...
Propagation of radiowaves over complex irregular terrain profiles at near-grazing angles is studied using an efficient numerical solver. In supporting signal coverage prediction for such specialized systems in which the transmitter and receiver are in extreme proximity to the ground, available studies have been limited to the dependence upon site-specific, empirical-based models. The usefulness of...
