Abstract

Photon tunneling effect and transmittance are investigated through the composite barrier of both positive index material and negative index medium with sinusoidal interface. Based on optical admittance and characteristic matrixes, the calculation method of transmittance is simplified. The seven-layer structure is proved to be effective in enhancing the photon tunneling. The transmittance resonance with the negative refractive index and amplitude of sinusoidal interface is analyzed. This method to generate transmittance resonance is significant when the width or thickness of the structure is restrictive.
