Traditional solar control applications rely on thin metal films to reflect EM radiation with wavelengths longer than that of the visible spectrum. Unfortunately such films also block radiation in cellular, GPS, and radio frequency bands. In one aspect, the disclosure provides a selectively-blocking filter that uses one or more optical filters tuned to a specific range(s) of wavelengths (e.g. for blocking IR radiation), while readily transmitting other wavelengths (e.g. both visible light and cellular/GPS signals). The filters can be manufactured on both flexible and rigid substrates.
