A CLASS OF PERIODIC STRUCTURES EXCITED BY APERIODIC SOURCES,

Abstract

A class of periodic structures are studied which have a periodically conducting slotted plane as one of the boundaries, when excited by a line source. This problem presents the difficulties which are characteristic to periodic structures excited by aperiodic sources. From the continuity of the fields in the slots, an infinite system of integral equations for the aperture fields is obtained. Under the assumption of narrow slots, the average of the electric and magnetic fields are related by expressions of the form of convolution. A sampling technique and a bilateral LaPlace transform permit obtaining a general formulation of this class of structures. (Author)
