A hybrid physical optics/method of moments numerical technique: theory, investigation and application

A hybrid physical optics/method of moments technique (PO/MoM) has been developed and implemented as described by Jakobus and Landstorfer (see IEEE Transactions on Antennas and Propagation, vol.43, no.2, p.162-9, 1995). This technique holds great computational advantages over conventional MoM techniques for practical engineering applications in the higher frequency range, i.e. when the dimensions of the scattering body are in the range of one wavelength or above. The theory behind the PO/MoM hybrid formulation as well as the applicability and accuracy of the technique are considered.
