利用线性全电磁波理论计算嵌入均匀、无损耗、无界热磁等离子体中的电天线的输入阻抗，该等离子体假定由热电子和冷离子组成。在计算热模式和热修正哨声模式的偶极辐射电阻时，分析中仅考虑电子的有限温度。在推导热等离子体偶极子输入阻抗的形式解时，使用了全波分析，并考虑了两种天线方向，即平行于和垂直于静磁场。推导了控制传播模式的一般色散方程，并对这些模式的传播特性进行了详细分析。
Use of a linear full electromagnetic wave theory to calculate the input impedance of an electric antenna embedded in a uniform, lossless, unbounded warm magnetoplasma, which is assumed to consist of warm electrons and cold ions. In calculating the dipole radiation resistance for the thermal modes and the thermally modified whistler mode the analysis includes the finite temperature only for the electrons. In deriving the formal solution of the warm plasma dipole input impedance a full-wave analysis is used and two antenna orientations are considered, parallel and perpendicular to the static magnetic field. A general dispersion equation governing the modes of propagation is derived and a detailed analysis is made of the propagation characteristics of these modes.
