A novel, high-frequency electronic chip potentially capable of transmitting tens of gigabits of data per second — a rate that is orders of magnitude above the fastest internet speeds available today —...
In oceans there are different ocean signals covering the multi-frequencies including tsunami, meteotsunami, storm surge, as sea level change, and currents. These signals have the direct and significan...
Surface elevation is a critical data for geo-science study. As far as some regions with rapidly-changing in landform, analyzing the surface elevation of different periods help provide scientific basis...
In this project, an analytical modeling of optically controlled Gallium Nitride has been presented here for an analysis of extrinsic and intrinsic parameters such as, gate capacitances including both ...
A chirped single-bandpass photonic filter is proposed improving the delay performance achieved by microstrip structures. Frequency range is extended up to tens of GHz since carrier-suppression-effect ...
The working frequency of the conventional electro-hydraulic vibration exciters, which consist of a servo valve and a hydraulic cylinder, is generally restricted within a narrow range due to limited fr...
Hourly measurements of atmospheric methyl chloride (CH3Cl) and methyl bromide (CH3Br), as well as some other halocarbons, were performed by using automated preconcentration gas chromatography/mass spe...
We discuss recently developed techniques for photonic analog-to-digital conversion based on nonuniform sampling. We have experimentally validated this approach, demonstrating high resolution, alias-fr...
A fiber-based approach for linear chirp control in optically-generated microwave pulses is proposed and demonstrated.Full linear chirp reconfigurability, including positive, negative and zero chirp ra...
Propagation modeling and simulation approaches for the use of High Frequency Surface Wave Radar (HFSWR) are discussed. HFSWR uses vertically polarized surface waves along multi-mixed paths in the lowe...
Realistic high frequency surface wave radar (HFSWR) targets are investigated numerically in terms of electromagnetic wave -- target interactions. Radar cross sections (RCS) of these targets are simula...
The increasing use of High Frequency Surface Wave Radar (HFSWR) for the surveillance of coastal regions is faced with the problem of limited channel availability in the electromagnetic spectrum. Thus,...
In today's resource-driven economy, maritime nations are claiming economic borders that extend beyond the continental shelf or the 200 nautical mile (nm) Exclusive Economic Zone (EEZ). However, claimi...
Surface Wave High Frequency Radars (SWHFR) are taken into account in the content of modeling and simulation challenges. Examples related to multi-mixed path surface wave propagation, radar cross secti...
A high-frequency (HF) capacitively coupled plasma reactor was developed to study the pyrolysis of waste tyre powder. The main objective was to generate a plasma at medium pressure and moderate tempera...
