TL;DR: It is demonstrated that a directed NLOS path scheme will make a terahertz communication system robust to shadowing, and it is shown that dielectric mirrors covering only parts of the walls will significantly enhance the signal coverage in a typical indoor scenario.

TL;DR: In this article, the reflectivity of smooth, optically thick materials can be modeled with Fresnel equations and a Rayleigh roughness factor calculated from the measured surface height distribution of the sample under observation.

TL;DR: In this paper, the frequency dependent refractive index and absorption coefficient of a variety of common building and plastic materials between 100 and 1000 GHz were measured for the modeling of bound media propagation phenomena including single and multiple reflections, transmission, diffraction and scattering effects.

TL;DR: A 300 GHz transmission system, designed for terahertz communication channel modelling and propagation studies, is introduced and consists of an autarkic transmitter and detector units based on Schottky diode mixer technology.

TL;DR: In this paper, an omnidirectional mirror for the terahertz range made from polypropylene and high-resistivity silicon is presented. But the structure is characterized by time-domain spectroscopy and the experimental data are in good agreement with transfer matrix calculations.
