Plane wave diffraction by a resistive step joining two parallel half-planes with different face impedances

Abstract

Plane wave diffraction by two impedance half-planes joined together by a resistive step is studied. By using the Fourier transform technique, the problem is formulated as a pair of uncoupled modified Wiener-Hopf equations and solved approximately. Numerical results illustrating the effects of various parameters such as step height, step resistivity, plate impedances, etc., on the diffraction phenomenon are presented.
