Effects of Turbid Media Optical Properties on Object Visibility in Subsurface Polarization Imaging
(The Optical Society of America, 2006-08)
, and anisotropy on image visibility were examined. Both linearly and circularly polarized light were used in the imaging. Three different types of target were investigated: scattering, absorption, and reflection. The experimental results indicate that target...
Applying the Polarization Memory Effect in Polarization-gated Subsurface Imaging
(The Optical Society of America, 2006-05)
Polarization memory is a well established phenomenon occurring when circularly polarized light propagates in turbid media of larger particles. Recent studies have demonstrated that the circularly crosspolarized imaging can significantly improve...
Ambipolar spin diffusion and D'yakonov-Perel' spin relaxation in GaAs quantum wells
(American Physical Society, 2009)
We report theoretical and experimental studies of ambipolar spin diffusion in a semiconductor. A circularly polarized laser pulse is used to excite spin-polarized carriers in a GaAs multiple quantum-well sample at 80 K. Diffusion of electron...
Anisotropic plasmons in a two-dimensional electron gas with spin-orbit interaction
(American Physical Society, 2009)
Spin-orbit coupling-induced anisotropies of plasmon dynamics are investigated in two- dimensional semiconductor structures. The interplay of the linear Bychkov-Rashba and Dresselhaus spin-orbit interactions drastically ...
Investigation of the presence of charge order in magnetite by measurement of the spin wave spectrum
(American Physical Society, 2006)
Inelastic neutron scattering results on magnetite (Fe3O4) show a large splitting in the acoustic spin wave branch, producing a 7 meV gap midway to the Brillouin zone boundary at q=(0,0,1∕2) and ℏω=43 meV. The splitting occurs below the Verwey...

Broadband beamforming and direction finding using concentric ring array
(University of Missouri--Columbia, 2005)
Sensor arrays have been used widely in applications including radar, sonar, seismology, biomedicine, communications and imaging. A very popular type of sensor array is circular array, which has almost invariant array pattern in azimuthal plane...
Correcting Optical-Axis Calculation in Polarization-Sensitive Optical Coherence Tomography
(IEEE Transactions on Biomedical Engineering, 2010-10)
Polarization-sensitive optical coherence tomography (PSOCT) has found many applications in imaging birefringence tissue samples. Polarization-sensitive detection is often implemented by utilizing a circularly polarized incident light and detecting...
Gravitational induction
(Institute of Physics, 2008)
We study the linear post-Newtonian approximation to general relativity known as gravitoelectromagnetism (GEM); in particular, we examine the similarities and differences between GEM and electrodynamics. Notwithstanding ...
Real and Virtual Competition
(Department of Economics, 2007)
model extending the circular city paradigm with two types of firms, conventional and electronic, is studied. Under the benchmark setting with only conventional firms in the market, each consumer visits the nearest store and purchases the product there...
Purification and characterization of A[beta] and probing the interactions between myricetin and A[beta] using various spectroscopic methods
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Worldwide, millions of people suffer from symptoms of memory loss and confusion associated with Alzheimer's disease (AD). Mounting evidence suggests ...
Ultra-wideband miniaturized microstrip patch antennas for wireless communications: design guidelines and modeling
(2013)
The number of wireless communication applications continue to increase steadily, leading to competition for currently allocated frequency bands. Capacity issues in form of data rate and latency have always been a bottleneck ...
Gravitomagnetism in the Kerr-Newman-Taub-NUT spacetime
(American Institute of Physics, 2003)
We study the motion of test particles and electromagnetic waves in the Kerr-Newman-Taub-NUT spacetime in order to elucidate some of the effects associated with the gravitomagnetic monopole moment of the source. In particular, ...
Propagation of polarized light in skeletal muscle
