Summary:
We present an experimental demonstration of surface plasmon induced transmission in the microwave region. A plasmonic material slab consists of a wire-medium metamaterial with metallic auxiliary elements. A coupling/decoupling between the TM-polarized plane wave and surface plasmons is achieved by placing diffraction gratings on both sides of the metamaterial slab. Numerical study shows the induced transmissions are attributed to dispersion relations of the metamaterial for surface plasmons and the periodicity of the diffraction gratings.
