Laser Services stocks and delivers custom laser cut microwave absorber material. One of our preferred brands is ECCOSORB® high loss microwave absorber from Emerson & Cuming. It is designed to attenuate electromagnetic interference by converting RF energy to heat.
Applications vary from free space to cavities, and so do the solutions. Free space applications include reducing reflectivity from a metal surface to building small test chambers, shaping antenna beams and antenna isolation. Cavity applications include reducing or eliminating cavity resonances, isolating components with insertion-loss-reducing harmonics, and terminating signals in waveguides.
