Complex ray analysis of beam transmission through two-dimensional radomes

Transmission through a radome is investigated using the complex ray technique. Ray tracing is performed along conventional trajectories as well as more accurate trajectories shifted laterally along the radome boundaries, and it is found from numerical comparisons that the conventional trajectories are adequate for the radome transmission problem. Wedge-tapered radomes are then considered, and the complementary roles of direct and collective treatment of internal reflections are made evident as the taper angle increases. The results establish the complex ray and collective transmission methods as an effective approach to treating radiation of large-aperture Gaussian-like fields of a dielectric radome.
