TL;DR: In this article, a tunable nanomechanical oscillator device and system is presented, which is designed such that injecting charge density into the tube (e.g. by applying a capacitively-cuopled voltage bias) changes the resonant frequency of the tube, and where exposing the resonator to an RF bias induces oscillitory movement in the suspended portion of the nanotube, forming a nanoscale resonator, as well as a force sensor.
Journal ArticleDOI
Electromechanical carbon nanotube switches for high-frequency applications
TL;DR: The fabrication and characterization of a nanoelectromechanical switch based on carbon nanotubes, which was measured to have speeds that are 3 orders of magnitude higher than MEMS-based electrostatically driven switches, with switching times down to a few nanoseconds, while at the same time requiring pull voltages less than 5 V.
Journal ArticleDOI
A compact dual-polarized 8.51-GHz rectenna for high-voltage (50 V) actuator applications
TL;DR: In this paper, a dual-polarized rectenna capable of producing a 50-V output voltage that can be used for driving mechanical actuators is described, and a circuit topology that allows the output of multiple rectenna elements to be combined in order to step up the output voltage.

Carbon nanotube array rf filter
TL;DR: In this article, a tunable nanomechanical filter system with an array of nanofeatures (18), such as nanotubes, is presented. And a method of producing a nanoscale RF filter (10) structure controllably positioned and oriented with a waveguide (14/16) and integrated electrodes (20) is also provided.
Journal ArticleDOI
A High-Power $Ka$ -Band (31–36 GHz) Solid-State Amplifier Based on Low-Loss Corporate Waveguide Combining
TL;DR: In this paper, a low-loss waveguide combining and a packaged monolithic microwave integrated circuit with a low loss microstrip-to-waveguide launcher is developed into a high power -band (31-36 GHz) amplifier producing 50 W at 33 GHz (Ka-band) using 32 low-power (>2 W) solid-state amplifier modules.
