摘要：
We propose a new method of exciting short-range surface plasmon polariton (SR-SPP) mode with a long-rang surface plasmon polariton mode, both of which are supported by a thin metal stripe embedded in a dielectric, using a double-sided anti-symmetric grating formed on the metal stripe. The effects of the metal stripe thickness, the grating corrugation depth and the number of grating periods on the transmission and reflection spectra are investigated numerically, and it is verified that light can be efficiently coupled to SR-SPP mode with the grating.
