Equivalent Surface Impedance of Slot Impedance Loads Designed on the Basis of Coupled Rectangular Cavities

摘要

A single two-dimensional slot impedance load (IL) formed by two coupled rectangular cavities connected through one or two holes with each other and with an open space is investigated. The case of H-polarization is considered. The problem is solved by the method of integral equations (IEs). The dependences of the equivalent surface impedance are calculated for different relations between geometric dimensions of the cavities and the wavelength.
