 | Like High Altitude Electromagnetic Pulse (HEMP), high power microwaves (HPM) produce intense energies, which may overload or damage various electrical system components such as microcircuits. This thesis investigates possible effects of a hypothetically designed HEMP-like weapon, an e-bomb, on electronically equipped target systems. The procedure to determine these possible effects is to estimate the electromagnetic coupling from first principles and simulations using a coupling model program (CEMPAT), pursuing a feasible ... |

| Fragmentation is characterized by a static arena test. In this test, fragmentation data are assembled in a Z-data file, which serves as input to lethality models and includes the velocity and angle of inclination of the warhead to estimate the lethal area of fragmentation. In this report, a new method to confirm the Z-data file and the lethality methodology is proposed. As a test case, the 105-mm high-explosive plastic round ... |

| Atmospheric turbulence has been shown to cause measurable effects on the propagation of electromagnetic radiation. These effects are significant at both visible/IR and microwave and millimeter wavelengths even though they vary as f7/6, where f is frequency. The contribution of the humidity structure function CQ 2 makes these effects significant for many applications in most wavebands of interest. In this paper we present results of calculations of the effects of ... |
