Surface Wave Absorbers
Surface Wave Microwave (RF) Absorbers are 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.

This materal is available in 305 x 305mm (12″ x 12″) and 610 x 610mm (24″ x 24″) sheets. However we can cut the sheets to shape and size as per your requirements. To indicate a required sheet size please add the suffix “-305” or “-610” accordingly.
It is available with and without PSA. If you require PSA please add the suffix “-PSA” to the required part number. For example for 0.5mm thick 610mm sheet Surface Wave Absorber with PSA the part number would be “MA-SWS-1-610-PSA”.
