Abstract :
Physical Optics (PO) has been used for a long time to compute RCS of targets and antenna radiation in situ, for structures larger than the wavelength. In this communication, problems as near field scattering, shadow region diffraction and cavity radiation are particularly investigated. Enhancements of PO to solve such large scale problems are presented, followed by validations obtained by comparison with measurements and exact method.
