Abstract: A window structure includes a metal layer that transmits microwave signals and reflects infrared signals. A microwave signal is a signal that has a frequency in the microwave spectrum of frequencies (a.k.a. the microwave frequency spectrum). The microwave frequency spectrum extends from 300 megahertz (MHz) to 300 gigahertz (GHz). An infrared signal is a signal that has a frequency in the infrared spectrum of frequencies (a.k.a. the infrared frequency spectrum, which extends from 300 GHz to 430 terahertz (THz)). The metal layer may be a discontinuous metal layer that's an electrically discontinuous metal layer and/or a physically discontinuous metal layer.
