A radome, an acronym coined from radar dome, is a structure placed over an antenna that protects the antenna from its physical environment. Ideally, the radome is radio-frequency (RF) transparent and does not degrade the electrical performance of the en-closed antenna. Today, radomes find wide applications in ground, maritime, aircraft, and missile electronic systems (Fig. 1).

Very early methods of radome evaluation were cumbersome, relying on the use of a nomograph (1, 2). With the advent of the personal computer (PC), geo-metric optics approaches based on PC computers were developed (3, 4). But with recent advances in the PC speed and capabilities, physical optics based surface integration approaches that previously required a mainframe computer can now be accomplished on a PC (5).
