Microwave Absorbers - Cavity Resonance

Cavity Resonance Absorbers are typically used in microwave cavity applications to attenuate oscillations, resonant frequencies or harmonics. These materials offer excellent attenuation at normal and high angles of incidence in the 1GHz to 20GHz range. Typically installed against a metallic substrate, Cavity Resonance Absorbers are made from silicone and are available in sheet stock or as application specific solutions.
