51. Empirical Modeling of Electromagnetic Accoustic Transducer Data
Report Number: 5087
Published: 8/1/1999
Authors: Kevin J Coakley, A V Clark, C S Hehman
Abstract: We characterize the observed phase and amplitude of acoustic birefringence data collected with an electromagnetic acoustic transducer (EMAT). Our characterization models are extended versions of an idealized model for acoustic birefringence. In the ...

53. Uncertainty Intervals for Polarized Beam Scattering Asymmetry Statistics
Published: 7/1/1993
Authors: Kevin J Coakley, Jabez J McClelland, Michael H Kelley, Robert Celotta
Abstract: In many scattering experiments, the quantity of most direct physical interest is a measure of the difference between two closely related scattering signals, each generated by a Poisson scattering process. This difference is often expressed in terms o ...

54. Micromagnetics of Domain Walls At Surfaces
Published: 1/1/1991
Authors: M Scheinfein, John Unguris, J L. Blue, Kevin J Coakley, Daniel Thornton Pierce, Robert Celotta, P J Ryan
Abstract: High-spatial-resolution magnetization maps of ferromagnetic surfaces are generated with use of scanning electron microscopy with polarization analysis (SEMPA). The structure of surface Neel walls is measured by SEMPA and compared directly to the res ...
