RFSS – Salisbury Screens
RFSS screen absorbers are thin, extremely lightweight absorbers that are optimized to provide a high degree of absorption for specific frequencies in the range of 1 to 18GHz. Construction consists of a conductive carbon coated “lossy” fabric, separated from a conductive ground plane by a low dielectric foam core. As a tuned (narrowband) absorber, the material must have an electrical thickness of 1/4 of a wavelength at the frequency of operation. This promotes signal attenuation by both energy dissipation within the “lossy” fabric material, as well as cancellation of the incoming and emerging signals at the surface, where they are 180 degrees out of phase. Through accurate control of the coating process used for the “lossy” fabric, absorption levels of greater than 20dB are easily and consistently achieved with a 10% bandwidth at the specified operating frequency.
This material is primarily used in airborne applications where weight savings are essential. It is used to reduce the interfering reflections in airborne radar applications or any antenna or signal environment that requires the suppression of random reflections at specified frequencies. To facilitate installation in application-specific areas, this material is readily supplied die-cut to specific shapes and sizes.
