Employing the dielectric tensor elements and taking into account the time variations of a rotating magnetic field (RMF) leading to the electric field generation responsible for particle acceleration, we develop a closed mathematical form for the radiated power absorbed by a long column containing multilayer inhomogeneous drift plasma with elliptical cross-section. To this end, cold-fluid equations are employed to drive explicit expressions for the dielectric tensor elements by taking into account the effect of RMF. Results reveal that the dielectric tensor has an anti-Hermitian part responsible for dissipation which comes from the rotation of external magnetic field. In order to describe the effective force exerted on the plasma, a general expression is obtained for the ponderomotive force by utilising the electric field components presented in this work. To check the accuracy of the obtained results, some limiting cases are discussed.

旋转磁场作用下漂移等离子体加热现象的一种新方法:介电张量中反荷米特部分的出现

利用介电张量元素并考虑旋转磁场(RMF)的时间变化,导致产生负责粒子加速的电场,我们针对包含多层不均匀漂移的长柱吸收的辐射功率建立了封闭的数学形式椭圆形横截面的等离子。为此,考虑到RMF的影响,采用冷流体方程来驱动介电张量元素的显式表达式。结果表明,介电张量具有一个反赫尔米特部分,该部分负责由外部磁场的旋转引起的耗散。为了描述施加在等离子体上的有效力,利用这项工作中提出的电场分量,可以得到关于动磁势的一般表达式。为了检查所获得结果的准确性,讨论了一些限制情况。
