A STUDY OF ARTIFICIAL DIELECTRICS

Abstract

The simulation of a plasma sheath using an artificial dielectric is studied in this investigation and is applied to an antenna geometry which is similar to some configurations encountered in aerospace applications. The antenna configuration is equivalent to a horn in an infinite ground plane with an unbounded plasma layer in front of the horn. The plasma layer is simulated by a rodded medium, and the radiation patterns of the antenna system are studied experimentally at 9, 10, and 11 KMC. The characteristics of a rodded medium are obtained both theoretically and experimentally. It is shown that a rodded medium not only simulates the isotropic characteristics of a plasma sheath but also the anisotropic characteristics of a plasma in an infinite steady magnetic field.
