Dual band millimeter-wave and infrared anti-reflecting coatings are presented, which enhance the passage of millimeter-wave and infrared radiation into a substrate material. A substrate is coated with a quarter-wave coating of an infrared anti-reflecting material followed by a quarter-wave coating of a millimeter-wave anti-reflecting material followed by a second quarter-wave coating of an infrared anti-reflecting material. The second infrared anti-reflecting coating enables incident infrared radiation to pass into the millimeter-wave anti-reflecting material, while minimizing reflection. The first infrared anti-reflecting coating enables incident infrared radiation from the millimeter-wave anti-reflecting material to pass into the substrate material, while minimizing reflection. The millimeter-wave anti-reflecting coating enables incident millimeter-wave radiation to pass into the substrate material, while minimizing reflection. All of the materials used are chosen to be millimeter-wave and infrared radiation permeable. Because the wavelength size ratio of millimeter-wave radiation to infrared radiation is on the order of 1000:1, the millimeter-wave anti-reflecting coating does not interfere, to the first order, with the transmission of infrared radiation, and the infrared anti-reflecting coating does not interfere with the transmission of millimeter-wave radiation.
