Theory of wave propagation in periodic structures

Abstract: By the generalized linear quantum transformation theory, we concisely derive the analytic expressions of partition function for general quadratic systems of multi-mode boson and fermion Fock space without any information for the energy spectrum. Under a general condition, we firstly acquire the exact expressions of energy spectra for these systems.PACS numbers: 03.65. Fd,

“…However, in case of the most frequently used BMs of the alternating pairs of layers with high contrast of the refraction index, the prediction error in this theory becomes quite high. The work [30] proposed a modified coupled-wave theory (MCWT) with considerably more extensive applicability, where the multiwave light diffraction is partially considered, especially in case of high diffraction orders, by changing the expressions for the coupling coefficients. Consideration of the multiwave diffraction allows to expand the MCWT applicability, which formally can be expressed as ε/ε 0 ≪ (πm) −1 + πm [29].…”

“…Однако в случае наиболее часто используемых БЗ из чередующихся пар слоев с большим контрастом показателя преломления погрешность предсказаний этой теории становится достаточно большой. В [30] была предложена модифицированная теория связанных волн (МТСВ) со значительно более широкой областью применимости, где осуществляется частичный учет многоволновой дифракции света, особенно в случае высоких порядков дифракции, за счет изменения выражений для коэффициентов связи. Учет многоволновой дифракции позволяет расширить область применения МТСВ, которую формально можно представить как ε/ε 0 ≪ (πm) −1 + πm [29].…”
