Abstract

The exact vector solution of far-field diffraction by a conducting strip is verified experimentally. Strips of 0.015- and 0.37-λ thickness were investigated. Results for both polarizations are compared for a strip of 2.85-λ width irradiated by a plane wave incident at glancing angles of 64°, 44°, and 24°. An approximate solution based upon Kirchhoff’s theory is compared with the vector formulation.
