文摘
- •
Absorption is enhanced in a broadband (0.3–9.9 μm) in a novel structure.
- •
Absorption is angle-insensitive and polarization-insensitive.
- •
Large thickness and period are favored to enhance a broadband absorption.
- •
Our structure is experimentally feasible and versatile for applied energy.
