Tunable Wideband Graphene based Filters in THz Band

In this paper, a procedure for analyzing and designing of tunable wideband band-pass and band-stop graphene based filters in the terahertz band is proposed. These planar wideband plasmonic filters are unique in their kind. With this procedure, it is possible to design filters with the desired functional characteristics in the form of the similar quarter-wavelength resonance stubs. The discontin...

THz LOCAL OSCILLATOR SOURCES

Planar GaAs Schottky diode based multiplier chains driven by HEMT power amplifiers have now demonstrated useful power beyond the 1 THz range. This paper will briefly review the state-of-the-art in planar Schottky diode multiplier chains for coherent detection. Future challenges and promising emerging technologies will also be outlined.

Generation of Tunable THz Pulses

Many phenomena in materials science, physics, chemistry, biology and medicine involve fundamental processes with a spectral signature in the THz range [20]. However, for many years, these processes have been little studied due to the lack of high quality THz sources. Fortunately, the recent developments in THz technology have filled this so-called THz gap [28]. With the emergence of reliable TH...

Frequency-tunable micromechanical oscillator

An experimental method, employing a scanning tunneling microscope ~STM! as an actuator and a scanning electron microscope ~SEM! as a motion detector, was developed to study microelectromechanical systems ~MEMS! and has been applied to study microfabricated cantilever beams. Vibrations actuated by an ac voltage applied to the piezodrive are transferred to the sample by the STM tip, which also pr...
