Study on current distribution and radiation characteristics of plasma antennas
等离子体天线表面电流分布与辐射特性研究

A surface-wave driven plasma antenna has been built. An exponential model of the surface current distribution has been proposed to calculate the radiation pattern of the plasma antenna. The results show that the plasma density decreases exponentially with the axial length. The magnitude of the imaginary part of the surface wave vector shows similar exponentially decaying profile with the plasma density under normal conditions, while the real part of the wave vector remains almost constant. The surface curre...
