摘要: Characteristics of a multiple-teeth-shaped plasmonic filter are analyzed. As an extension this structure, asymmetrical structure is proposed and numerically simulated by using the finite difference time domain method with perfectly matched layer absorbing boundary condition. It found that can realize function narrow-passband filter. The central wavelength passband linearly increases simultaneous increasing d1 d2.
