Lossy Foam

ARC Technologies LS series is a low density, high-loss, carbon impregnated open-cell foam - LS is available in various thicknesses and amounts of carbon loading - allowing the series to be effective over a broad range of frequencies (500MHz to 40GHz) and in most cases provides ≥5 dB loss. The LS series can be split into two main forms; flexible (for easier conformity) and rigid (for machined cuts).

LS is mainly used for far-field requirements and in a multi-layer form optimising the use of various carbon loadings in layers. Applications include crosstalk reduction, antenna shrouding, shadowing of parts for radar cross section measurements, shadowing of components for anechoic chambers and broadband absorption.

LS is available in sheets, is easily handled and is a relatively cost-effective solution. LS can be weather sealed for outdoor protection and coatings can be added to provide resistance against water, jet fuel, hydraulic fuel and gasoline. LS is halogen free, RoHS and REACH compliant.
