Optical Scattering
Absorber
● Research details
Absorbing films are devices in which the incident radiation at the operating wavelengths can be efficiently absorbed, and then transformed into ohmic heat or other forms of energy. They play an important role in various applications, such as thermoelectric, invisibility, solar-thermal-energy harvesting.
In recent year, the technology progress at nanofabrication have spurred many breakthroughs in the field of photonic metamaterials that provide efficient ways of manipulating light–matter interaction at subwavelength scales. As one of important applications, photonic metamaterials can be used to implement novel optical absorbers. Based on our recent progress in this field, we will study spectral design of absorption film and they further the potential application.
