Gain of Object/Slot Array On Infinite Cylinder Operating At Fundamental Cavity Modes

Warne, Larry K.; Langston, William L.

This report examines the coupling into a circumferential slot array on an infinite cylinder with a finite length interior cavity operating at the fundamental cavity modal frequencies. The directivity gain associated with the interior cavity field is examined, and in this frequency range (as well as lower frequencies), is found to be enhanced by the exterior short circuit current variation with angle driving the slots.
