Abstract
An interference type radar attenuator is described formed of a plurality of thin sheets having selected admittance values. The sheets are spaced apart by thin plastic spacer members having a shape memory so that the sheets can be compressed together by deforming the plastic spacers for very tight packaging and, upon release of the packaging, the sheets return to a spaced relation for effective radar attenuation. A similar structure is useful in space vehicles for thermal shielding and as a meteroid bumper.
