MAST Technologies’ Surface Wave Absorber product series is a thin very highly loaded sheet stock having high loss at microwave frequencies, while maintaining the desirable characteristics of elastomeric binders. Surface Wave Absorbers are the most heavily magnetically loaded absorber. Surface Wave Absorbers are designed to exhibit the highest loss and are intended to be applied to metal surfaces for traveling or surface wave attenuation. Surface Wave Absorbers attenuate traveling wave energy at frequencies from 1 GHz to 20 GHz. The standard elastomer for this product series is silicone, but other elastomer formulations are available which may be better suited for specific environmental conditions.
