Abstract

Two methods of reduction of microwave power reflection from a wood stack are studied theoretically. The first method consists in choice of such slope angle of the radiating aperture at which a phenomenon of the Brewster takes place. The second method is based on application of the metal grid located between an radiator and a stack. The optimum relations for a choice of a grid cell size and a grid location are obtained.
