  • Abstract
    Enhanced scattering of the THz radiation caused by the interaction of near field component with plasmons in a substrate material results in sub-wavelength resolution within THz range. Variation of dielectric permittivity of organic materials placed on a metal substrate can improve contrast of the image obtained with such a technique.
