Abstract

To analyze the radiation of a monopole covered with plasma, a shift operator method in FDTD is applied. By using this scheme we compute the radiation of a monopole antenna with the coverage of plasma. We observe from the numerical results that the plasma can greatly absorb electromagnetic waves and can impede the Gaussian pulse travelling along the antenna. In addition, the high frequency components in the radiation fields are decreased, and the resonant frequencies are shifted.
