Attitude Determination from Single-Antenna Carrier-Phase Measurements
Thomas B. Bahder
A model of carrier phase measurement (as carried out by a satellite navigation receiver) is formulated based on electromagnetic theory. The model shows that the phase of the open-c…
Chaotic Free-Space Laser Communication over Turbulent Channel
N. F. Rulkov, M. A. Vorontsov, L. Illing
The dynamics of errors caused by atmospheric turbulence in a self-synchronizing chaos based communication system that stably transmits information over a 5 km free-space lase…
170 Nanometer Nuclear Magnetic Resonance Imaging using Magnetic Resonance Force Microscopy
Kent R. Thurber, Lee E. Harrell, Doran D. Smith
We demonstrate one-dimensional nuclear magnetic resonance imaging of the semiconductor GaAs with 170 nanometer slice separation and resolve two regions of reduced nuclear spin pola…
Temperature measurement at the end of a cantilever using oxygen paramagnetism in solid air
Kent R. Thurber, Lee E. Harrell, Doran D. Smith
We demonstrate temperature measurement of a sample attached to the end of a cantilever using cantilever magnetometry of solid air ``contamination'' of the sample surface. In experi…
Spin polarization contrast observed in GaAs by force-detected nuclear magnetic resonance
Kent R. Thurber, Lee E. Harrell, Raul Fainchtein +1
We applied the recently developed technique of force-detected nuclear magnetic resonance (NMR) to observe 71Ga, 69Ga, and 75As in GaAs. The nuclear spin-lattice relaxation time is…
