Low-THz overhead power cable signatures: The effect of surface features on Low-THz reflectivities

Abstract

The measurements presented in this paper show that feature extraction can be used to identify objects of interest by making use of the scattering present and angular resolution available when using low TeraHertz (low-THz) (0.1 THz-1 THz) devices. The results shown were obtained by measuring two different types of overhead power cables of similar size but with different surface structure which causes the backscatter from each type of cable at 150GHz to be distinct. The measurements are supported by simulations made that incorporate Bragg mode theory.
