Transmission of a Transient electromagnetic plane wave through a grating of circular cylinders

An analysis of the transmission of a transient electromagnetic plane wave through a grating formed by an infinite array of circular cylinders is presented. Emphasis is placed on the transient shielding characteristics of the grating for various cylinder spacings and angles of incidence. The transient results are obtained by first obtaining analytical experssions for the fields in the frequency domain and then performing a numerical inverse Fourier transformation. Some physical interpretations of the shielding effectiveness of the grating are given.
