Abstract: One or more devices for absorbing electromagnetic radiation are disclosed. The one or more devices include a substrate comprising a glass material. The substrate also includes a first pattern of a metal layer formed on a first surface of the substrate and a second pattern of a metal layer formed on a second surface of the substrate. The first pattern and the second pattern are different and features of the first pattern and the second pattern can be tunable to maximize optical transparency of the one or more devices and to maximize absorption of electromagnetic radiation having a target range of frequencies, such as one or more ranges of frequencies within the microwave portion of the electromagnetic spectrum.
