Surface plasmon polariton power divider using metallic gratings

We propose a dividing method of the power of surface plasmon polariton (SPP) propagating along a metal film based on metallic gratings. By placing gratings on the top and under the bottom of the metallic film and varying the off-set distance, grating height, and filling factor, the power of SPP can be divided with specific ratios.
