Electromagnetic plane waves in an isotropic absorbing chiral medium (chiral metamaterial) are considered. The Drude–Born–Fёdorov system of constitutive equations with complex values of the permittivity, the permeability, and the chirality parameter is applied. The difference between forward and backward normal waves is delineated by the introduction of a special parameter – the wave type identifier. Analytical expressions for the real and imaginary parts of the wave numbers of homogeneous normal waves are presented.

具有损耗的电磁超手性各向同性介质中的法向波

考虑了各向同性吸收手性介质（手性超材料）中的电磁平面波。应用了具有复数值介电常数、磁导率和手性参数的本构方程的 Drude-Born-Fёdorov 系统。前向和后向法向波之间的区别是通过引入一个特殊参数——波浪类型标识符来描述的。给出了齐次法向波波数实部和虚部的解析表达式。
