Abstract : The document presents a theoretical and experimental investigation of the transmission coefficient of a periodically apertured plane conducting screen for all angles of incidence. Equations are formulated by variational methods and equivalent circuit concept. Measurements as well as calculations are made to verify the theoretical analysis. Numerical results of the equivalent susceptance for normal incidence are included and discussed. The results can be important in the further study of the design of a fenestrated metal radome and rain erosion metal cap and other applications. (Author)
