MAST Technologies designs develops and manufactures RF microwave and EMI absorbing materials for integration into military & electronics solutions. We are equipped with a spacious elastomer processing suite for batch mixing calendaring compression molding flat sheets and complex parts precision sanding and custom die-cutting. Tuned frequency absorbers or resonant frequency absorbers provide reflection loss at a discrete frequency typically offering 20dB of attenuation. Tuned frequency absorbers offer narrow band absorption from 1 to 40 GHz. Cavity Resonance Absorbers are designed to exhibit high loss within a microwave cavity. The absorber will in effect lower the Q factor of the cavity by attenuating cavity oscillations resonant frequencies or harmonics. Cavity resonant absorbers attenuate energy at normal and high angles of incidence at frequencies from 1 to 20 GHz.
