Abstract:

Research on microwave propagation, reflection, absorption and backscatter in XUV excimer laser 193 run and microwave 2.45 GHz produced plasmas has been carried out. Our research on high density, low temperature ne 5 x 10exp 13cu cm, 1 eV laser-created plasma and broadband 1-3 GHz microwave transmission, absorption and backscatter between two antennas in a plasma are described. Research on the creation of a laser produced sheet beam plasma for either a low loss, rapidly scanable agile microwave mirror reflector 10 GHz or a diffuse, lossy absorber is being carried out. Measurements and theoretical analysis of these topics are described. We also discuss our collaborations with other research groups and our theoretical and computational research to support and interpret the experimental observations.
