Integral equation solution and RCS computation of a thin rectangular plate

In this work, a new integral equation is employed to calculate the current distribution on a rectangular plate which is illuminated by a plane wave. Numerical results are also obtained for the radar cross section (RCS) of the plate for different angles of incidence and different dimensions of the plate. These results are compared with other RCS computations using geometrical theory of diffraction, physical optics, and variational methods.
