Cuming Microwave C-RAM SS Frequency-Tuned Salisbury Screen Absorber

C-RAM SS is a thin, very light weight, frequency tuned absorber which provides high absorption at specific frequencies.

C-RAM SS is a Salisbury Screen type absorber which is made from a conductive front layer, a dielectric core (or spacer) and a reflective back layer.

The dielectric core is a closed cell polyethylene foam of low loss and low dielectric constant. A reflective aluminum foil back layer is bonded to this core. The front layer is a fiberglass cloth with a lossy coating, it is bonded to the dielectric spacer. This construction provides high tear strength, good abrasion resistance and light weight.

C-RAM SS is readily cut to size with scissors or a band saw. It is well suited to reducing reflections from nearby objects, increasing isolation between adjacent antennas and reducing energy levels of antenna sidelobes.

TYPICAL PROPERTIES 

C-RAM SS is available for frequencies from 1 GHz through 12 GHz. High frequency versions can be fabricated on request.
