Broadband Polarization-Independent Perfect Absorber Using a Phase-Change Metamaterial at Visible Frequencies
We report a broadband polarization-independent perfect absorber with wide-angle near unity absorbance in the visible regime. Our structure is composed of an array of thin Au squares separated from a continuous Au film by a phase change material (Ge(2)Sb(2)Te(5)) layer. It shows that the near perfect...
