Abstract
An attenuator of electromagnetic radiation, such as radar, is described wherein a single attenuator sheet in the nature of "spacecloth" is placed in front of a plurality of reflective layers wherein each of the reflective layers is tuned to reflect a narrow band of radiation of a selected frequency and transmit other frequencies; and each of the reflective layers is spaced from the attenuation layer at a distance of one-fourth of the wavelength of electromagnetic radiation to which it is tuned. In a preferred embodiment each of the reflective layers comprises elongated narrow conductive areas arranged in spaced apart columns and rows in a generally non-conductive area.
