The Penetrated and Scattered Field Distributions in the Presence of a Nonuniform Cold Magnetized Plasma Column Surrounded by Multiple Apertures: TE-Wave Incidence

Abstract

Due to a TE-wave normal incidence, the penetrated and scattered fields in the presence of a nonuniform cold magnetized plasma column are investigated in this work. The mathematical treatment is based on the direct integral equation formulated for describing the currents on the surrounded multiple apertures of the plasma column. To formulate such an integral equation, two-dimensional magnetic dyadic Green's functions in multilayered cylindrical shells are derived in terms of the cylindrical vector wave functions. By using Galerkin's method, the magnetic currents on all apertures are expanded in the form of a series of Chebyshev polynomials of the first kind, and furthermore, parameter effect studies are performed to show the variation of the near- and far-zone fields with the changing of the operating frequency, angular width, and number of the surrounded apertures.
