Abstract Absorption and emission in isotropic one-dimensional photonic crystals with continuous distribution of the refraction index have been investigated. It was assumed that the photonic crystal under investigation was fabricated by introducing micro and nano-scale particles (either ferroelectric or ferromagnetic, or both) into a specially chosen liquid and it is periodically inhomogeneous with respect to both the dielectric and magnetic properties. The peculiarities for the absorption, emission and light localization were investigated. The absorption suppression in the photonic band gap was demonstrated. Anomalously strong absorption and anomalously weak absorption (or the anomalous increase in the intensity of the light transmitted through a crystal or, simply, the Borrmann effect) were observed near the band edges, depending on either the absorption due to the imaginary part of the dielectric permittivity or the imaginary part of the magnetic permeability. These effects were exhibited stronger for periodic inhomogeneity of absorption. The effects are different for the absorption changes in-phase and out-of-phase in the real part of the corresponding permeability or permittivity. The features of the revealed effects for the oblique incidence of the light were also investigated.

具有折射率连续分布的一维元液体的吸收

摘要 研究了折射率连​​续分布的各向同性一维光子晶体的吸收和发射。假设正在研究的光子晶体是通过将微米和纳米级粒子（铁电或铁磁，或两者）引入特别选择的液体中制造的，并且它在介电和磁性方面是周期性不均匀的。研究了吸收、发射和光定位的特性。证明了光子带隙中的吸收抑制。在带边缘附近观察到异常强吸收和异常弱吸收（或通过晶体传输的光强度的异常增加，或者简单地说，鲍曼效应），取决于介电常数的虚部或磁导率的虚部引起的吸收。对于吸收的周期性不均匀性，这些效应表现得更强。对于在相应磁导率或介电常数的实部中同相和异相吸收变化的影响是不同的。还研究了光斜入射的显示效果的特征。
