Abstract:

Reduction of the reflection coefficient of dipole absorbers for oblique incidence of electromagnetic waves was investigated. To complete the theory of reflection by the additional system of dipoles, the propagation of electromagnetic waves in an artificial absorbing medium consisting of infinitely long parallel wires with small conductivity was studied. Measurements were made with centimeter waves using a parallel-platetransmission line to determine the equivalent propagation constants of the medium by scanning the electric field with respect to amplitude and phase. The propagation properties of the parallel wire medium are explained with a theory deduced from an analogy to line-theory. Author
