Generation of laser radiation of difference frequency in a rectangular millimeter waveguide

Abstract

Dislocation mobility in quasicrystals is calculated using basic thermodynamic and hydrodynamic equations. The dependence of the dislocation mobility on viscosity, vacancies and phasons is given. It is shown that the phasonic defects make the major contribution to the inverse mobility of the free segments of dislocations.

GENERATION OF THz RADIATION IN NONLINEAR CRYSTAL PARTIALLY FILLING A HOLLOW WAVEGUIDE

“…For transmitting the THz radiation from the source to the object and then to the detector it is necessary to utilize different guided structures, such as hollow metallic waveguides [1][2][3] , solid wires 4 , copper coated flexible hollow polycarbonate waveguide 5 , metallic sl-3ot waveguide 6 , one-dimensional (1D) Bragg waveguide 7 , parallel-plate waveguides 8 , dielectric waveguide 9 , surface plasmon polariton waveguides [10][11] and ribbon-based dielectric waveguides 12 .…”
