Electrostatic Model for Antenna Signal Generation From Dust Impacts

Electrostatic Dust Detection and Removal for ITER

We present some recent results on two innovative applications of microelectronics technology to dust inventory measurement and dust removal in ITER. A novel device to detect the settling of dust particles on a remote surface has been developed in the laboratory. A circuit board with a grid of two interlocking conductive traces with 25 μm spacing is biased to 30 – 50 V. Carbon particles landing ...

Broadband THz Generation from Photoconductive Antenna

Since the observation of radiation in the Terahertz (THz) frequency range from photoconductive antennas exited by femtosecond (fs) laser pulses, considerable efforts have been made to understand the mechanism responsible for THz generation, and to develop applications in THz Time-Domain Spectroscopy (THz-TDS). In this paper, the calculation of THz radiation from biased photoconductive antenna i...

Technologies for laboratory generation of dust from geological materials.

Dusts generated in the laboratory from soils and sediments are used to evaluate the emission intensities, composition, and environmental and health impacts of mineral aerosols. Laboratory dust generation is also utilized in other disciplines including process control and occupational hygiene in manufacturing, inhalation toxicology, environmental health and epidemiology, and pharmaceutics. Many ...

Multiple - Antenna Signal

Optimal antenna and signal co-design for UWB antenna link Short title: Optimal antenna & signal co-design

Antennas are a critical component of UWB link because of radical changes in signal waveform/spectrum on its way between transmitter and receiver. Antenna, circuitry and signals need to be designed collectively to send efficiently signals of pulsed energy between transmit and receiver antennas. Such a co-design approach is demonstrated in this work through pulse shaping for achieving required te...
