Abstract

Development of surface plasmon (SP) spectroscopy method in teraHertz (THz) spectral
range (30-100 сm 1 or 0.1-10 THz) utilizing free-electron laser (FEL) radiation is described
in the paper. The following issues are considered in it: 1) methods for THz SP excitation by
bulk radiation, as well as the ways of measuring their characteristics; 2) experimental results
on THz SP excitation on aluminum and copper surfaces by FEL radiation with wavelength of
110 and 150 m; 3) the procedure for the sample material THz dielectric constant calculation
using the measured SP complex refractive index; 4) a number of methods implementing THz
SP spectroscopy technique.
