MAST Technologies’ Convoluted Foam Absorber product series is a lightweight conductive carbon loaded sheet stock providing broadband reflection loss at microwave frequencies. Due to the shape of the cones on Convoluted Foam 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.
