Paper Abstract

The fields refracted by circular symmetric hyperbolic lens illuminated by a linearly polarized wave incident obliquely on the aperture are calculated from the induced surface currents. It is shown that the fields in the axial region are almost same as the fields in the aperture of corrugated horn under balanced hybrid conditions. The image structures for different focal ratio are compared with the classical Airy pattern, deduced by scalar analysis, of optical focusing systems. The coupling between the lens and a corrugated horn at different position on focal plane are also considered.
