Abstract

In this letter, a theoretical model is proposed to calculate the coupling efficiency of surface plasmon polaritons (SPPs) by a single slit on the metal film. In contrast to previous work developed for normal incident light only, TM0 and TM1 modes of the slit are incorporated in the model, which makes it applicable for the case of oblique incidence. Numerical simulations confirm that this two-mode model can accurately predict the coupling efficiency of SPPs by slits with subwavelength widths (
