Abstract: This disclosure relates to dielectric chaff materials or fibers which are small in character for packing and expandable on release to produce clouds of great cross section. Polymer materials are treated chemically and/or irradiated with nuclear or electronic radiation which partially decomposes the polymer. Upon release, the polymer is heated to create gas bubbles from within which expand the dielectric fibers to change the density and shape of the dielectric.

Abstract: A method of mounting silicon solar cells in a planar array that not only lds electrical insulation between cells but allows for a multifold increase in thermal dissipation of the cell array, comprising metallizing a wafer of beryllium oxide on each side so that the outer surface is copper, etching the wafer on one side so that the only metallized parts which remain are those on which the solar cells are to be mounted or wiring is to be attached, soldering the solar cells on the unetched copper prominences, coating the aluminum panel on which the cells are mounted with a copper layer, soldering the underside of the wafer on the upper surface of the aluminum panel with soft solder such as indium, and covering all remaining passive surfaces with a teflon F.E.P. tape the underside of which carries a layer of slver and then a layer of inconel metal.
