Cerenkov and sub-Cerenkov radiation from a charged particle beam
(Monterey, CA; Naval Postgraduate School, 1987) Neighbours, John R.; Buskirk, Fred R.; Maruyama, Xavier K.; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); Naval Postgraduate School (U.S.); Physics
As a consequence of the relaxation of the phasing conditions between the moving charge and radiated wave for finite beam path lengths, the Cerenkov peak is broadened and the threshold energy is developed which is applicable to charged beams consisting of single point charge or charge bunch of finite size, as well as beams consisting of periodically repeated bunches
A perturbation theory for light diffraction from a bigrating with multiple surface-polariton excitation
(Monterey, CA; Naval Postgraduate School, 1986-12) Glass, Nathaniel E.; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); Naval Postgraduate School (U.S.); Dept. of Physics
A perturbation theory has recently been developed for treating the diffration of light, with surface polariton resonant excitation, from a bigrating surface. The theory is an approximation, to first order in the grating height, of an earlier theory based on the Rayleigh hypothesis. The perturbation theory holds for arbitrary polarization and for arbitrary plane of incidence with respect to the grating directions. It is, however, limited to treating only the possibility of two simultaneous resonant evanescent waves, whereas four are possible at normal incidence on a square grating, and three are possible on a rectangular grating. The present work generalizes the earlier work to allow for a four fold (or three fold) resonance. This extension also allows one now to determine the complex dispersion relation for surface-polaritons, for wavevectors at the intersection of two Brillouin zone boundary lines (not possible in the previous formulation).

Application of Color Coding in Tactical Display S-3A
(Monterey, California. Naval Postgraduate School, 1980-04) Neil, Douglas E.; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); Operations Research
The present effort was designed to examine the literature on color coding in terms of the incorporation of color in tactical displays aboard the S-3A. Available literature could be conveniently separated into work concentrating on visual functioning, display/environmental factors, task/performance variables. Overall the results do not strongly support the inclusion of color in S-3A tactical displays. In the event color is incorporated, its usage should be at the control of the operator.

Observation of microwave Cerenkov radiation as a diffraction pattern
(Monterey, CA; Naval Postgraduate School, 1985-08-01) Maruyama, Xavier K.; Neighbours, John R.; Buskirk, Fred R.; Snyder, D. D.; Bruce, Robert G.; Vujaklija, Milorad; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); Naval Postgraduate School (U.S.); Physics
Measurement of microwave Cerenkov radiation in air exhibits the diffraction pattern predicted in earlier work. The radiation appears only at harmonics of the frequency of periodic electron bunches, angular distribution power measurements are presented for frequencies of 2.86, 5.71, 8.57 and 11 & 12 GHz corresponding to the fundamental and the first three harmonics of an S band RF linac
