Scientists have discovered new magnetic surface that is able to reflect infrared light. This material was thought to be non magnetic, but closer studies revealed that it was in fact magnetic and was able to reflect infrared light. Scientists can use nanoscale antennas to harness this radiation from the reflected surface. This has exciting uses in the sensor, solar cell and laser industries. Things that react or work off of infrared radiation, such as tv remotes, could be revolutionised by using reflective mirrors that can increase the strength of the signal from the remote to the TV, thus increasing the desired distance between the remote and the receiver.
