Radiation From Magnetic Line Source Covered with a Moving Sheath

In this paper we investigate the radiation from magnetic line source covered with a moving uniaxial or isotropic sheath (nondispersive dielectric or cold plasma). The far‐zone radiated fields and the radiation pattern for the four cases, (a) uniaxial dielectric sheath, (b) isotropic dielectric sheath, (c) uniaxial plasma sheath, and (d) isotropic plasma sheath are obtained, and the effects of the motion of the sheath on the far‐zone radiated fields and the radiation pattern for each case are discussed by showing some numerical results of the radiation pattern.
