EeonFoam(TM) Lossy Foams

EeonFoams(TM) are open-cell polyurethane foams coated with conducting polymer formulations. Thicknesses from 1/4" to 6" can be treated.
Transmission losses at 3 GHz can vary between less than 1 dB to over 30 dB per inch. Gradients through the foam thickness are possible. Foam pieces
much larger than 2'x2' can be treated.
