Improving Physical Optics Approximation Through Bessel Beam Scattering

In this letter, the scattering of a nondiffractive Bessel beam (BB) incident field by a perfect electric conducting circular cylinder is investigated and compared with the standard scattering solution by a plane wave. It is proven that the BB incident field improves the validity of standard physical...
