Subject and Purpose. The sources of errors are identified that may arise in the course of terahertz-range measurements of the dielectric constant of weakly absorbent dielectrics, if performed within the surface plasmon resonance (SPR) technique. Poss

Resonance diffraction of THz hidrogen cyanide laser radiation on a semiconductor (InSb) grating is studied both experimentally and theoretically. The specular reflectivity suppression due to the resonance excitation of the THz surface plasmon-polarit

It is shown that the resonance features analogous to the well known optic Wood-type anomalies can be observed in the THz region for diffraction at periodically profiled semiconductor surfaces. The analytical theory of such resonance processes caused

We present a productive method of designing specific diffraction gratings that ensure some predetermined energy redistributions between outgoing waves. It is based on the analytical solution of the direct and reverse diffraction problems under surfac

The problem of diffraction by simultaneously existing surface-profile and impedance gratings in the presence of resonance with a surface electromagnetic wave is examined. The problem is solved in an impedance approximation (Leontovich boundary condit
