 | This report describes the results of a study of the fundamental issues in electromagnetic scattering theory with an emphasis on pole behaviors of a lossless sphere arising from the singularity expansion method (SEM). Mie theory is used to solve the acoustic and electromagnetic scattering problems for spheres with lossless boundary conditions and an incident plane wave. It is shown that, for certain lossless sheet impedance boundary conditions there exist second ... |

| This final technical report reviews the research activities during the period of this grant, emphasizing the final year. The key finding of our study is that the total incident electron dose is a critical parameter affecting secondary electron emission (SEE). A completely automated experimental set-up was implemented that allowed for measurement of secondary electron yield (SEY) as a function of beam energy, angle of incidence of primary electrons, electron dose, ... |

| Pulsed power is a technology that is suited to drive electrical loads requiring very large power pulses in short bursts (high-peak power). Certain applications require technology that can be deployed in small spaces under stressful environments, e.g., on a ship, vehicle, or aircraft. In 2001, the U.S. Department of Defense (DoD) launched a long-range (five-year) Multidisciplinary University Research Initiative (MURI) to study fundamental issues for compact pulsed power. This research ... |

|
| High Power Microwave (HPM) and Vacuum Electronics (VE) sources have been studied in support of Air Force needs, under the auspices of the MiPRI initiative, a congressionally mandated program. A consortium of three universities led by the University of New Mexico and including the University of Michigan and MIT have teamed up to perform research on two sources of current interest to the Air Force: i) the relativistic magnetron operating ... |
