Perfect Light Absorption: Discovery Could Lead to Even Smaller Devices
“Absorption of electromagnetic energy is at the heart of many modern devices. Reducing the size of the absorbers will make the devices themselves much smaller. We hope that the results of this research will be useful in the creation of compact microwave and optical antennas, as well as efficient wireless energy transfer devices,” concludes Andrey Bogdanov.
