Response of Graphene Based Gated Nanodevices Exposed to THz Radiation

EPJ Web of Conferences, 2015
In this work we report on the response of asymmetric graphene based devices to subterahertz and terahertz radiation. Our devices are made in a configuration of a field-effect transistor with conduction channel between the source and drain electrodes ...

Proposal for an electrically controlled terahertz micro-oscillator

AIP Advances
A source that generates sustained terahertz electromagnetic radiation (oscillator) controllable by an applied voltage is proposed. The structure consists of a nanocomposite slab containing metal nanorods enclosed between two graphene sheets, which are ...

Plasmonic antennas based on rectangular graphene nanoribbons with controlled polarization of terahertz and infrared radiation

Физика волновых процессов и радиотехнические системы
Background. To develop new terahertz wireless communication systems with high throughput and transmission speeds, such as 6G and above, effective control of the polarization direction of emitted terahertz waves is necessary, but most methods are ...

Terahertz Cherenkov radiation induced by a self-modulated electron beam in plasma wakefield

AIP Advances, 2019
In this paper, a novel scheme of generating terahertz radiation is proposed, which considers a relativistic electron beam being modulated by its self-excited plasma wakefield in a plasma-filled slow-wave structure (SWS).

Atmospheric Propagation of Terahertz Radiation

, 2012
Terahertz (THz) radiation, sandwiched between traditional microwave and visible light, is the electromagnetic spectrum with the frequency defined from 0.1 to 10 THz (1THz=1012Hz). Until recently, due to the difficulty of generating and detecting techniques in this region, THz frequency band remains unexplored compared to other range and tremendous ...
