Abstract

A new method has been proposed for determining the complex refractive index of terahertz surface plasmons. This method implements the concept of asymmetric static interferometry in the planar version, where the interference pattern is formed by surface rather than bulk waves. The information about the real part of the refractive index is carried by the interference pattern period, while its imaginary part can be found from the illumination magnitudes in the pattern extrema.
