FIG. 2.

The distribution of electric fields inside and outside the lens structures, which are placed in a PEC horn antenna, under the excitation of a line-current source. (a) The lens is composed of layered homogeneous material defined in Eqs. (8)–(10). (b) The lens is composed of layered homogeneous material defined in Eqs. (11) and (12). (c) The lens is composed of inhomogeneous and anisotropic materials defined in Eqs. (16)–(19). (d) The collimating lens is made of regular dielectric.
