Abstract : Radar is a sensitive detection tool and since its development, methods for reducing microwave reflections have been explored. Radar absorbers can be classified as impedance matching or resonant absorbers. Radar absorbing materials are made from resistive and/or magnetic materials. Circuit analog materials give more design freedom through access to capacitive and inductive loss mechanisms. Dynamic absorbers can tune the absorption frequency through control of resistive and capacitive terms. Many conductive and magnetic materials have been trialed for absorption including carbon, metals and conducting polymers.
