SCATTERING CHARACTERISTICS OF A RECTANGULAR GROOVE IN A REACTIVE SURFACE

The diffraction of a plane electromagnetic wave by a rectangular groov e in a reactive plane is studied rigorously through the Fourier transf orm technique. The corresponding boundary value problem is Formulated into a modified Wiener-Hopf equation of the third kind whose approxima te solution involves two sets of infinite number of unknown constants satisfying two infinite systems of linear algebraic equations. Numeric al solutions of these systems are obtained for various values of the s urface reactance and the sizes of the groove through which the effects of these parameters on the diffraction phenomenon are studied.
