A new iterative method for scattering problems

Abstract: A new iterative method for scatterng problems is presented. This method is based on the tact that cutoff waves excited by a given source are shunted by pure reactive impedance and we consider that such waves come back to the source. This approach is applied to many scattering problems by perfectly conducting bodies and seems to be efficient, particularly in the range where the obstace dimensions are comparable to the wavelength. SummaryIterative methods have been developed in the

“…n is the outward unit vector normal to the considered interface. The analytical expression of the iterative process involves a system of two equations: one written in the spatial domain (2), characterizing the boundary conditions at the interface of the structure through the operatorŜ; the other expressed in the modal domain (3), describing the upper and lower media through the operatorΓ [13]. A Fast Modal Transform (F M T ), and its inverse (F M T −1 ), ensure conversions between both domains [14].…”
