Devices for efficiently coupling electromagnetic radiation in the far infrared and sub-millimeter microwave regions of the electromagnetic spectrum to surface electromagnetic waves comprise a material of negative dielectric constant having a grating contoured surface overcoated with a transparent organopolymeric material. The efficiency of coupling between the free radiation and the surface electromagnetic waves can be optimized by adjusting the thickness of the overcoating layer.

Grating surface plasmon coupler

A device for efficiently coupling electromagnetic radiation in the far-infrared and submillimeter spectral regions to surface plasmon waves comprises a prism constructed of a dielectric material, a first layer integrally formed on one face of the prism having an index of refraction which is less than the index of refraction of the prism, and a second overcoat layer formed integrally on the first layer and having an index of refraction which is greater than the index of refraction of the first layer.
