Controlling Electromagnetic Surface Waves with Scalar and Tensor Impedance Surfaces.
(2013)
The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional ...
Designing Thermal Modulators for Portable GC x GC Systems.
(2015)
Microelectromechanical systems (MEMS) have the advantage of scale and can be manufactured in bulk. One of the active areas of MEMS research is the development of micro-scale comprehensive two-dimensional gas chromatography ...
HgCdTe Auger-Suppressed Infrared Detectors Under Non-Equilibrium Operation.
(2009)
A nearly universal goal for infrared photon detection systems is to increase their operating temperature without sacrificing performance. The limiting factor for cooling requirements is the dark current in the detector ...
Structural Characterization and Impedance Spectroscopy of Substituted, Fused-Ring Organic Semiconductors.
(2011)
Organic materials present a number of advantages over silicon that make them ideal candidates for modest performance devices like active matrix backplanes and RFID tags. The work detailed here describes both structural ...
Nonholonomic Virtual Constraints and Gait Optimization for Robust Robot Walking Control.
(2016)
Bipedal locomotion is well suited for mobile robotics because it promises to allow robots to traverse difficult terrain and work effectively in man-made environments. Despite this inherent advantage, however, no existing ...
Plasma Discharges in Gas Bubbles in Liquid Water: Breakdown Mechanisms and Resultant Chemistry.
(2015)
The use of atmospheric pressure plasmas in gases and liquids for purification of liquids has been investigated by numerous researchers, and is highly attractive due to their strong potential as a disinfectant and sterilizer. ...
High Resolution Lithography-Compatible Micro-Electro-Discharge Machining of Bulk Metal Foils for Micro-Electro-Mechanical Systems.
(2009)
The application of batch mode micro-electro-discharge machining (µEDM) to the fabrication of micro-electro-mechanical systems has opened the door to lithographically compatible precision machining of all bulk metals. High ...
Fundamental and Applied Electrochemistry for Photonic Applications
(2020)
Photonic devices that selectively transmit or reflect light are highly desirable in a wide variety of applications, including energy harvesting, aesthetic decorations and optical displays. However, most of these high ...
Characterizing Heliospheric and Interstellar Interactions Using Pickup Ion Measurements
(2022)
The Heliosphere, orbiting the galactic center of the Milky Way, is a plasma bubble carved out of the Local Interstellar Medium (LISM) by the Sun's dynamic and magnetic influence. Its relative motion creates a steady inflow ...
Optimization and Model-predictive Control for Overload Mitigation in Resilient Power Systems.
(2013)
The National Academy of Engineering named the electric power grid the greatest engineering achievement of the 20th century. However, as recent large-scale power grid failures illustrate, the (electro-mechanical) electric ...
