This paper presents an overview of THz-technologies, and especially their use for communications. Different approaches on the physics of THz radiation are discussed, from the Radio Frequency (RF) perspective, as well as from the Far Infrared (FIR) optic signals’ perspective and Nano electronics’ and molecular electronics’ perspective. Experiments with THz Continuous Wave (CW) frequency domain spectroscopy are presented. The goal of the experiment was to determine a frequency band with constant received power, high Signal to Noise Ratio (SNR) and no water absorption lines near such potential frequency band. From spectroscopy experimental result suitable frequency bands with bandwidth of 20 GHz to 50 GHz were found, what promises the possibility of achieving high communication data rates in next few years of several hundred Gb/s over distances about 1 km using THz waves. So, the relations between transmission media spectroscopy measurements and channel amplitude frequency characteristic was shown. From the instrumentation description it is also evident that, the experimental platform used is suitable for research and, as well for the education purpose, in communications’, sensors’, and materials’ courses and related curses. |
