Inhomogeneous waves generation for the electromagnetic deep penetration into lossy media

The generation of inhomogeneous electromagnetic waves in a lossless medium is generally associated to leaky-wave antennas. In the present paper it is shownhow such waves can be also easily generated bythe transmission of a homogeneous wave through a dissipative dielectric layer. In particular,a dissipative triangular prisminthe free space, whose first interface is fedby ahomogeneous wave can be employed to generatean inhomogeneous wave emerging atthe second interface. The phase and attenuation vectors obtained are evaluated against the geometry and the material of the prism.The results illustrate a novel approach in generating inhomogeneous waves in lossless media which finds applications for the deep penetration of lossy materials.
