DIELECTRIC- PLATE WAVE GUIDE.

Abstract

The field in a dielectric wave guide which consists of two lossless dielectric plates placed parallel to each other in free space and excited by an infinite electric line source located exactly mid-way between the two plates is formulated in terms of an infinite integral. The solution of the infinite integral by using the method of contour integration yields the conditions under which the structure behaves as a surface waveguide and or leaky wave guide. Theoretical results are confirmed by experiment.
