ANTENNA LOBE SUPPRESSION. VOLUME VI. DIFFRACTION BY CONDUCING WALLS OF FINITE THICKNESS.
Abstract
Diffraction of thick walls is computed by the superposition of wedge diffractions. A new method for computing certain wedge diffractions is derived in series form of cylindrical wave functions to overcome deficiencies in Fresnel integral form. Diffraction characteristics of certain wedges are computed by both forms as functions of wedge geometry. A new technique is employed to formulate simultaneous linear equations for solving unknown coupling coefficients among wedges of a thick wall. The coupling coefficients thus solved are used to obtain continuous radiation patterns of different configurations of a thick wall. Thick wall diffraction is applicable to reduction of backlobe radiation of aperture antennas. In this regard, the electromagnetic compatibility of a thick wall for use of typical horn antennas is discussed. (Author)
