Three-dimensionally curved, knit wire electromagnetic wave reflector

Abstract: An electrically conducting, electromagnetic wave reflector comprises a knit wire reflecting surface consisting of two superimposed knitted wire meshes. The wire mesh reflector is impregnated with a transparent thermo-setting resin so that the metallic structure is no more than 3 mils from the outer surface of the reflector. The knitted wire mesh permits the fabric to be smoothly stretched over a three-dimensional surface of predetermined shape. The two wire meshes are staggered with respect to each other to reduce the effective size of the openings between the loops of the mesh. A reinforcing structure preferably consisting of two layers of glass cloth impregnated with a thermo-setting resin is utilized to provide a lightweight reflector substantially impervious to environmental corrosion. The resulting structure may be used as an antenna or reflector and is suitable for the microwave region such as the K band.

Random band models with lines of pure Doppler shape.

Abstract: The behavior of random band models composed of lines of pure Doppler shape for several irradiance distribution functions is investigated. The particular irradiance distribution functions chosen are: (1) constant irradiance, (2) exponential distribution, (3) truncated S−1 distribution, and (4) the exponential-tailed S−1 distribution. The curves of growth for the first two models are found to have the asymptotic (log)12 behavior characteristic of an isolated Doppler line while the latter two models show a (log)32 dependence.
