Deskripsi
Recent studies highlighted deep-penetration properties of inhomogeneous waves at the interface between a loss-less and a lossy medium. Such waves can be generated bymeans of radiating structures known as Leaky-Wave Antennas (LWAs). Here, a different approach is proposed basedon the use of a lossy prism capable to generate an inhomogeneous wave when illuminated by a homogeneous wave. Thelossy prism is conceived and designed thinking of Ground-Penetrating Radar (GPR). The results achieved by the lossyprism will be compared with those obtained by means of a previously designed LWA that was created with the identical objective. The approach of this paper is purely theoretical, and it aims at providing basic ideas and preliminary results usefulfor an innovative LWA design.
