Abstract

In this paper we give a mathematical derivation of the coordinate dependence of the propagation constant of an electromagnetic wave propagating in a moving dielectric, which by definition is a bianisotropic medium. The need for such an investigation consists in the requirement to describe the medium in numerical simulation. In this context, special clarifications are given on the accuracy, stability, and variability of the expression obtained. In this paper, both inertial and noninertial (rotational motion) reference frames are considered. Results proving the correctness of the expressions presented. The obtained expression makes it possible to obtain the value of the propagation constant in the vicinity of a local source of electromagnetic waves on the surface of a moving medium.
运动介质传播常数的坐标表达式
本文给出了电磁波在运动介质中传播常数与坐标关系的数学推导。根据定义,运动介质是双各向异性介质。这种研究的需要在于需要在数值模拟中描述介质。在这种情况下,对所获得的表达式的准确性、稳定性和可变性进行了特殊说明。本文考虑了惯性参考系和非惯性参考系(旋转运动)。结果证明了所提表达式的正确性。所得到的表达式使得在运动介质表面的局部电磁波源附近的传播常数的值成为可能。
