Analysis of resonant transmission of light through a subwavelength metallic nanoslit surrounded by various medium

We investigate the resonant transmission of light through a sub-wavelength metallic nanoslit surrounded by various medium. The relationship between the resonant wavelength through a sub-wavelength metallic nanoslit and refractive index of surrounding medium is obtained and the distributions of magnetic field intensity at the resonant peaks are numerical simulated by boundary integral method. The results show that there exists a linear relationship between the resonant transmission and the refractive index of surrounding medium. This analysis will provide useful information in nano-sensor technology.
