Nikram microwave absorption film suppresses noise from high-frequency electronic devices with bands over 2GHz. Noise suppression rating is greater than 30dB for GHz bands greater than four. Thin Nikram film reduces incoming and outgoing noises by mounting it on the surface of any housing; does not require grounding. Can allow metallic devices to become stealth against radar searches. Is 42.5µm thick; absorbs microwaves effectively. Suppression rates of the microwaves absorbed are 20dB at 2GHz, 30dB at 4GHz, and stable for frequencies greater than 4GHz. Does not reflect microwaves at the surface.
