摘要
We report an epsilon-near-zero (ENZ) material based polarization-insensitive electrotunable metamaterial absorber, which comprises a patterned-metal-insulator-metal based nanostructure. The numerical simulations show that coupling of electrically-induced ENZ-mode to the gap-plasmon resonance- mode enables more than 80% average absorbance over 1500-1800 nm wavelength regime and similar to 10-dB modulation-depth at 1550 nm.
