磁电双折射的再认识
Magnetoelectric birefringence revisited
摘要：
研究了电磁波在介电系数分别为$\varepsilon_{μν}(E,B)$和$μ_{μν}(E,B)$的各向同性介质中的传播。程函近似的制度被认为是。采用场扰动的Hadamard方法，通过求解菲涅耳方程得到色散关系。一些应用的形式主义。特别地，推导并讨论了由外加场引起的双折射现象。结果表明，只要物理系统满足一定的条件，即使不存在克尔效应和Cotton-Mouton效应，也可以产生磁电双折射效应。
英文摘要：
Electromagnetic wave propagation inside isotropic material media characterized by dielectric coefficients $\varepsilon_{μν}(E,B)$ and $μ_{μν}(E,B)$ is examined. The regime of the eikonal approximation is considered. The Hadamard method of field disturbances is used and the dispersion relations are obtained by solving the Fresnel equation. Some applications of the formalism are presented. Particularly, birefringence phenomena induced by applied external fields are derived and discussed. It is shown that magnetoelectric birefringence effect can occur even without the presence of Kerr and Cotton-Mouton effects, provided the physical system satisfies certain conditions.
