Quasi-Optic Studies of Dielectric Radomes and Lenses.
Abstract
This grant has been concerned with work on the tranmission and guiding characteristics of dielectric radomes and lenses. Emphasis has been placed on novel techniques that promise: (a) to facilitate the near-to-far field transition calculations for highly collimated distributed aperture fields, and (b) to facilitate the systematize ray-optical treatment of multiple reflections inside the radome, of curvature effects, of wave trapping, and guiding, etc. In case (a), the investigation centered on complex ray methods. In case (b), it lead to a new and rigorous procedure for treating the prototype cylindrical shell Green's function in terms of ordinary and composite ray fields, with the latter accounting collectively for multiple internally reflected rays. The accomplishments suggest that these procedures offer a promising new approach to the radome problem.
