平面波在电磁PQ介质中的传播

Plane-Wave Propagation in Electromagnetic PQ Medium

Ismo V. Lindell

摘要:

将最近定义的两类基本电磁介质(P介质和Q介质)推广到PQ介质。本文研究了平面波在一般PQ介质中的传播,并应用四维并矢形式导出了解析形式的四次频散方程。通过考虑PQ介质的各种特殊情况,其色散方程已知分解为两个二次方程或相同满足(无色散方程的介质),验证了结果。作为数值例子,考虑了具有不可分解色散方程的PQ介质的色散面。

英文摘要:

Two basic classes of electromagnetic media, recently defined and labeled as those of P media and Q media, are generalized to define the class of PQ media. Plane wave propagation in the general PQ medium is studied and the quartic dispersion equation is derived in analytic form applying four-dimensional dyadic formalism. The result is verified by considering various special cases of PQ media for which the dispersion equation is known to decompose to two quadratic equations or be identically satisfied (media with no dispersion equation). As a numerical example, the dispersion surface of a PQ medium with non-decomposable dispersion equation is considered.
