Title :
A Pitfall in the Scalar Electromagnetic Formulation of Kirchhoff Theory
Abstract :
A difficulty in applying scalar Kirchhoff diffraction theory to the individual components of the vector electromagnetic field is pointed out. For example, the method, if applied incorrectly, does not account for the cross-polarized radiation from a circumferential slot on a cylindrical structure.
