Dependencey of resonant wavelength on the width of subway elength metallic slits: analysis and modulation
The variation trend of the resonant wavelength of a subwavelength metallic slit with respect to its width has been investigated by using the Fabry-Perot model. It is determined by two antagonistic factors related to the effective refractive index and the phase of reflection. We show that the trend can be changed by directly modulating the dielectric constant of the structure. Our analysis is supported by the numerical simulation based on the finite-difference time-domain technique.
