Broadband Polarization-Insensitive Absorption In Solar Spectrum Enhanced By Magnetic Polaritons

A broadband polarization-insensitive solar absorber with simple structure based on metamaterials is proposed. The excitation of SPPs, MPs and CMPs enables a wide plateau exceeding absorbance of 90%, which is favorable for solar harvesting.;A broadband polarization-insensitive solar absorber with simple structure based on metamaterials is proposed.
