| Summary: | This paper rigorously studies the resonant transmission of electromagnetic waves around embedded trapped modes in bianisotropic films and derives the dispersion relations, the embedded mode condition, and the coupling and tunneling of the evanescent wave within the reciprocal lossless bianisotropic layer. The Berreman's matrix model has been developed to obtain the transmission characteristics through the bianisotropic film. When the layer structure was perturbed, a resonance phenomenon was perceived around the distinct trapped modes; these resonances lead to anomalous transmission and field amplifications around the trapped mode frequencies. The parameters of the magnetoelectric tensors can be used to control the number of the trapped modes and accordingly the resonances in the bianisotropic layer material. |
