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 ...
Development of a Time-Resolved Laser-Induced Fluorescence Technique for Nonperiodic Oscillations
(2016)
Time-resolved measurements of ion dynamics could be key to understanding the physics of instabilities, electron transport, and erosion in Hall thrusters. Traditional measurements of the ion velocity distribution in Hall ...
Numerical Study of Coronal Mass Ejections, Shocks, and Turbulence: from Chromosphere to 1 AU.
(2014)
My dissertation focuses on one of the major source of destructive space weather: coronal mass ejections (CMEs). By helping develop and utilizing a new data-driven global MHD model: The Alfven Wave Solar Model (AWSoM) in ...
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 ...
Discrete Ordinates Methods for Transport Problems with Curved Spatial Grids.
(2015)
The method of characteristics (MOC) has been favored for many recent whole core transport codes; some current research codes are: the nTRACER code from Seoul National University, the MPACT code from the University of ...
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. ...
Liquid Drop Actuation by Photoelectrowetting
(2017)
In electrowetting an electric potential is applied between a droplet of electrolyte and a conductor separated by an insulator. The repulsion of like charges deforms and spreads the droplet until capillary and electric ...
