| Abstract: | A gaseous plasma column as an efficient radiator of electromagnetic waves is well known. This paper presents the scattering
analysis of a plasma antenna using the conjugate gradient fast Fourier transform (CG-FFT) method. Radar cross sections (RCS)
of designed plasma antenna for different plasma parameters are computed mainly. Numerical results show that the plasma antenna
with appropriate parameters can offer lower RCS than the metal one. It is evident from the observed scattering characteristics
that the plasma antenna can be regarded as a rod of imperfect conductor with losses. |
