Interference aspects of terahertz transmission

In this paper, interference aspects of terahertz transmission are considered. Possible interference effects in indoor THz communication are experimentally proved using a THz photomixer setup. The method of coherent homodyne detection is applied to explain the problem. Fourier Transform is used for precise analysis of the interference effects and calculations of the optical path changes. The paper explains the problem of multipath communications in the terahertz range.
