Splitting of a Tamm plasmon polariton at the interface between a metal and a nanocomposite layer conjugated with a photonic crystal (Bragg mirror) has been theoretically investigated. The splitting can be implemented when the Tamm plasmon polariton frequency approaches the resonance frequency of the nanocomposite, which consists of metallic nanoballs dispersed in a transparent matrix. The reflectance spectrum of the $p$-polarized waves at the normal incidence of light has been calculated. It has been established that the Tamm plasmon polariton splitting significantly depends on the concentration of nanoballs in the nanocomposite layer and its thickness. The solution of the dispersion equation derived for a sample with semi-infinite mirrors has been compared with the spectra obtained for a finite structure by the transfer matrix method.

在金属和与光子晶体共轭的共振纳米复合材料层之间的界面处分裂 Tamm 等离子体激元

在金属和与光子晶体（布拉格镜）共轭的纳米复合材料层之间的界面处，Tamm 等离子体激元的分裂已经在理论上进行了研究。当塔姆等离子体激元频率接近纳米复合材料的共振频率时，可以实现分裂，纳米复合材料由分散在透明基质中的金属纳米球组成。$p$的反射光谱- 已计算出光垂直入射时的偏振波。已经确定，Tamm 等离子体激元分裂显着取决于纳米复合材料层中纳米球的浓度及其厚度。将半无限镜样品的色散方程的解与通过传递矩阵法获得的有限结构光谱进行了比较。
