Plane electromagnetic waves in layered periodic dielectric structures.

摘要

Several analytic methods are used to derive and discuss analytic expressions for electromagnetic wave fields in finite one-dimensional layered structures. A new modification is obtained for the so-called multiple reflection method. Special attention is given to layered periodic dielectric structures. The systematic dependence of the reflection coefficient on the parameters characterizing this type of structure is studied in detail, using the two-layered periodic dielectric structure as a typical example. A general method for the construction of the Greenu27s function for finite one-dimensional layered structures is developed. The sum of the total Neumann (Born) series is calculated for sufficiently simple cases of perturbations in the profile of the refractive index. Using the Greenu27s function, the influence of fluctuations of the width of the basic layers on the reflection and transmission of electromagnetic waves propagating through the two-layered periodic dielectric structure is investigated. The results are applied to the design of optical switching systems with periodic dielectric structures as the operating medium.Dept. of Physics.
