METHOD OF INCREASING PROPAGATION LENGTH OF INFRARED MONOCHROMATIC SURFACE ELECTROMAGNETIC WAVES ON FLAT METAL SURFACE Russian patent published in 2016 - IPC G02B6/10 H04B10/80 H04B17/391 

FIELD: information technology.

SUBSTANCE: invention relates to information-communication technologies, particularly, to increase in length of propagation of infrared monochromatic surface electromagnetic waves (SEW) along flat metal surface. Method includes application of non-absorbing dielectric layer on surface. Before layer application direction of maximum beam pattern of bulk electromagnetic waves (BEW) emitted by SEW from their track is determined. Layer thickness and refraction index of its material is selected so that presence of layer provides increment of real part of module of SEW vector by value where k_o = 2π/λ - wave number BEW in surrounding surface medium; λ is wavelength of radiation in environment; φ_Max is angle of deviation of maximum beam pattern from plane surface.

EFFECT: technical result consists in increase of propagation length (SEW) and providing its protection against external effects.
