Convoluted Foam Microwave RF Absorbers are a lightweight conductive carbon loaded sheet stock providing broadband reflection loss at microwave frequencies. Due to the shape of the cones on Convoluted Foam Microwave Absorbers, they exhibit high reflection loss and are intended to be applied to metal surfaces inside test boxes, housings, radomes, network enclosures, or antennae. Reticulated Foam Absorbers attenuate energy at normal and high angles of incidence at frequencies from 1 GHz to 18 GHz.
Convoluted Foam Microwave RF Absorbers are a premium quality tapered broadband microwave absorber. It is a moderately flexible urethane foam material having a front surface cut to a convoluted (egg-carton) shape. Because of the rounded convolutions and lack of sharp corners and points, it is the preferred absorber for mm wave frequencies and for very wide incidence angles. There is no degradation in performance at incidence angles out to 60° off-normal.
