Abstract :
The optimization of a submillimeter wave hologram type of compact antenna test range (CATR) is studied with a combined analysis of an exact near-field aperture integration (physical optics) and a finite difference time domain (FDTD) method at 500 GHz. The effect of altering the feed horn radiation pattern is discussed.
