5) A square metallic plate of size 102X10 is kept centered in the xy plane. A y-polarized uniform plane wave incident from the positive z-axis illuminates the plate. Assuming that the plate is a perfect conductor, obtain the physical optics current induced in the plate. Determine far fields scattered by the plate and sketch it in the xz and yz planes.
