Microwave Electrometry with Rydberg Eletromagnetically Induced Transparency in Vapor Cells
(2016-07-20)
An atom-based approach is presented to detect absolute microwave (MW) electric fields (E-fields). The approach uses Rydberg atoms in vapor cells at room temperature. The MW E-field measurements utilize a bright resonance ...
Digital signal processing on the unit sphere via a Ramanujan set of rotations and planar wavelets.
(2000)
We give a sufficient condition for a zonal function to be a strictly positive definite. A major result of this thesis is that we have proven Shreiner's result as a consequence of a more general representation-theoretic ...
Error-correction coding for high-density magnetic recording channels.
(2004)
Finally, a promising algorithm which combines RS decoding algorithm with LDPC decoding algorithm together is investigated, and a reduced-complexity modification has been proposed, which not only improves the decoding ...
Towards Efficient and Enhanced Wireless Coexistence in the Unlicensed Spectrum
(2021-07)
The 3rd Generation Partnership Project (3GPP) is developing the fifth generation (5G) of wireless broadband technology and has identified the unlicensed spectrum as a principal item on the plan of action. Listen-Before-Talk ...
Carbon Nanotube Enhanced Lithium Ion Composite Cathodes
(2014-08-13)
Batteries are sought that can deliver high energy density and high power density over thousands of cycles, with minimum environmental impact and cost. Invariably no one material can achieve all of these requirements. Lithium ...
GROWTH OF WIDE BANDGAP SEMICONDUCTORS USING PULSED ELECTRON BEAM DEPOSITION (PED) PROCESS
(2015)
Wide bandgap materials hold a great potential in solid state lighting, power electronics, and radio frequency (RF) device applications. The cumulative market for all these applications is forecasted to be approximately $75 ...
Spectral analyses of the dual polarization Doppler weather radar data.
(2007)
Echoes in clear air from biological scatterers mixed within the resolution volumes over a large region are presented. These echoes were observed with the polarimetric prototype of the forthcoming WSR-88D weather radar. The ...
III-V and Thin Film Photovoltaics for Extraterrestrial Application
(2019)
Photovoltaic power is one of the few options available for electrical devices stationed outside of our atmosphere. As the satellite market turns to smaller satellites based on the CubeSat and SmallSat form factor, these ...
A STATE VECTOR AUGMENTATION METHOD FOR INCLUDING VELOCITY INFORMATION IN THE LIKELIHOOD FUNCTION OF THE SIR VIDEO TARGET TRACKING FILTER
(2016)
This thesis is focused on visual target tracking. Visual target tracking has been widely studied. The main idea is to be able to determine the target's location from a video sequence. Techniques such as the Kalman Filter ...
Microwave filters for next generation radio frequency transceivers
(2023-08-04)
Increased data rates in wireless communications enforce unprecedented performance metrics on the front-end filters to operate in crowded spectral bands. These requirements include strong selectivity, low insertion loss, ...
