A new plasma antenna of beam-forming

Abstract

In this paper, a new plasma antenna of beam-forming is investigated based upon the interaction of plasma elements due to the incident electromagnetic wave. It presents a study of the multiple scattering from argon plasma cylinders rigorously applying boundary value method, grounded on the properties of electromagnetic wave transmitted in the argon plasma. Approximate expressions for the total radiation of plasma antenna in the far field are derived briefiy. Such a novel plasma antenna of beam-forming, according to the research, exhibits interesting performance in terms of radiation efficiency, beam-forming and beam-scanning. Valid results are brought forth to demonstrate the capabilities of such antenna of two scales. Comparisons are given in detail as well.
