Towards Future THz Communications Systems
Carrier frequencies beyond 300 GHz, belonging to the so-called THz range, have received attention for considering this frequency band for future multi-gigabit short-range communication systems. This review paper gives an overview of current issues in the emerging field of THz communications targeting to deliver wireless 100 Gbps over short distances. The paper will start by introducing scenario...

متن کاملNumerical Study on THz-Wave Generation and Detection of Field-effect Transistor
A numerical study on the FET-based THz wave generation and detection is presented in this paper. The numerical method is derived directly from the hydrodynamic equations and implemented in Matlab coding. Simulation results are compared with the existing theories, proving the validity of the developed numerical method and providing useful data that the THz detection theory cannot yield. Keywords...
متن کاملDetection of nanosecond-scale, high power THz pulses with a field effect transistor.
We demonstrate detection and resolution of high power, 34 ns free electron laser pulses using a rectifying field effect transistor. The detector remains linear up to an input power of 11 ± 0.5 W at a pulse energy of 20 ± 1 μJ at 240 GHz. We compare its performance to a protected Schottky diode, finding a shorter intrinsic time constant. The damage threshold is estimated to be a few 100 W. The d...
