The first parabolic reflector Rl i s in the Fresnel (near) field of the feedhorn. Also, the second reflector RZ current-intogration (POICII formulation for noar field, the is in the near field of the R1. Using physical-optics currents induced on R1 and RZ may be computed. The radiation pattern exit from R2 is then calculated. This rnehod, though Capable of producing proper esults, is extrcmely time-consuming and costly.
