We consider the electromagnetic field due to the reflection and transmission of a plane wave by a bounded periodic structure containing chiral layers. The problem is solved using the 2x2-block-representation transfer-matrix formulation. The frequency and angular dependences of the reflection and transmission coefficients are given. The boundaries of the passbands and stopbands are determined from the basic-element transfer-matrix eigenvalue analysis.

The scattering coefficients of a finite quasiperiodic Fibonacci sequence for the incident wave of perpendicular and parallel polarization are obtained using the matrix polynomials methods. The structure consists of isotropic layers and thick periodic grates of magnetodielectric bars. The grates are placed either orthogonal or parallel to each other. Each grate is approximated as a layer of anisotropic medium with some efficient permittivity and permeability tensors. Closed-form formulae for the scattering coefficients are obtained. The location of quasi-stop and quasi-pass bands and the conditions of resonant structure transparency are determined.

Abstract-A series of N identical periods of pairs of isotropic and biisotropic layers with defect in j-th basic element is investigated. The universal method that simultaneously allows to taking into account different types of defects in the structure is proposed. The problem is solved using the circuit theory and the transfer matrix methods. The analysis of the dynamic of electromagnetic properties of the investigated structure was carried out for different types of defects.
