A new flexible material developed by engineers at the University of California, San Diego (UCSD) is claimed to be able to tune out various portions of the electromagnetic spectrum while allowing others to pass through, such as being opaque to infra-red but transparent to visible light, for example. This material has the potential to vastly improve the efficiencies of solar cells, or create window coatings that not only let in visible light and keep out heat, but also stop electronic eavesdropping by blocking electromagnetic signals.
