On the Modified Theory of Physical Optics
Basic features of the modified theory of physical optics (MTPO) are discussed on the example of scattering at perfectly reflecting half-planes and wedges. It is shown that violations of theExpand

Comments on "Improvement of the PO-MoM Hybrid Method by Accounting for Effects of Perfectly Conducting Wedges"
In the above paper U. Jakobus and F. M. Landstorfer (see ibid., vol.43, p.1123-9, Oct. 1995) state that their approach is opposed to the physical theory of diffraction (PTD), which, according toExpand
