“…The boundary is remarkable for the fact that no depolarization occurs when fields of circular polarization are scattered at it [13]. The boundary conditions under which tangentials to a certain preferred direction on the surface components of the electric and magnetic field strengths vanish, are also referred to as the conditions of artificially soft and hard surfaces [14].…”

“…13 pode-se concluir que no material quiral, apos a remocao do pulso de excitacao a polarizacao do campo eletrico estabiliza girando continuamente no sentido horario, olhando no sentido do eixo de propagacao. A ocorrencia de um unico modo na res posta espectral e a rotacao uniforme do campo estabilizado no sentido horario evidenciam a presenca de apenas uma das duas solucoes naturais do meio bi-isotropico, a que apresenta polarizacao circular no sentido horario, distinguida pelo subscrito "+" [I ], [8]. 0 valor do Indice de refracao equivalente para esta solucao, obtido atraves da analise de ondas planas propagando em meios bi-isotropicos, e de n; = ~ f.1 /" r + K"= -J1,249J9+0.37673",1,491L que e 0 valor assintotico das curvas de dispersao no grafico da Fig.…”

Abstract-The transmission and reflection coefficients of electromagnetic waves propagating through the finite periodically layered chiral structure are defined both theoretically (using the propagation matrix method) and experimentally. The coefficients of the propagation matrix of the periodically layered chiral medium are obtained. The boundaries of the forbidden bands for a periodic medium, whose unit cell consists of two different chiral layers were determined. It is shown that the boundaries of the forbidden bands do not depend on the chirality parameter of the layers. It is found that for certain values of the layers thicknesses, the forbidden band widths tend to zero and that the proposed method for calculation of the reflection and transmission coefficients can be used to determine the effective constitutive parameters of artificial chiral metamaterials. The transmission and reflection coefficients of plane electromagnetic waves propagated through the finite periodically layered chiral structure were determined experimentally for 20-40 GHz range. A good agreement between the experimental results and theoretical studies of the forbidden band spectrum for the structure under research has been shown.
