Performance Evaluation Facility for LADARs

Author(s)
Geraldine S. Cheok, William C. Stone
The use and scope of LADAR (laser detection and ranging) applications continues to expand as the technology matures. This growth is reflected in the National...

Microfabricated alkali atom vapor cells

Author(s)
Li-Anne Liew, Svenja A. Knappe, John M. Moreland, Hugh Robinson, David C. Larbalestier, John Kitching
We describe the fabrication of chip-sized alkali atom vapor cells using silicon micromachining and anodic bonding technology. Such cells may find use in highly...

Dipole Moment of a Pb-O Vacancy Pair in PbTiO3

Author(s)
Eric J. Cockayne, Benjamin P. Burton
The polarization of a nearest-neighbor (nn) Pb-O vacancy pair in PbTiO3 is calculated, using the modern theory of polarization, implemented in the density...

Generation and Transport of Smoke Components.

Author(s)
Kathryn M. Butler, George W. Mulholland
Smoke is a mixture of gases and suspended particulate matter, or aerosols. The nature of the aerosol component of smoke can play a significant role in the...
