Abstract

The terahertz band, which is located between the microwave and the infrared bands, has shown countless assets that have allowed researchers to make huge advances in different sectors. In this paper, we try to present an overview of terahertz digital and analog applications in some areas such as communication, material characterization, and imaging. Terahertz communication systems deliver data rates of the order of TBps, allowing data-intensive applications to operate more quickly. Terahertz spectroscopy can detect chemicals or liquids that are difficult to identify with other techniques, using FTS (Fourier transform spectroscopy). Terahertz rays offer very high image resolution thanks to their wavelength. Applications include medical imaging, protein detection, the effects of radiation on biological processes, disease diagnosis and the analysis of the optical properties of human tissues. In the field of security, the detection of illicit or dangerous objects is done by short pulses lasers. Finally, TD non-destructive spectroscopy makes it possible to observe and preserve cultural heritage through short laser pulses. In the field of terahertz communication systems, we will present the simulation results of an active bandpass filter at the frequency 129 GHz. This filter has the particularity of being tunable over a 300 MHz band.
