On the accuracy of physical optics
Abstract
The first-order correction to the physical optics (PO) solution for the axial radiation field from parabolic reflector antennas is found. The correction is of order 1/k and is in quadrature with the PO solution. By means of the correction term the accuracy of the PO surface integral is found to be better than 0.22 times the square of the wavelength/diameter ratio dB on axis. Thus, the PO solution for the wavelengths.
