摘要A metal-dielectric composite metasurface of the broadband epsilon-near-zero property is designed with the nanoscale airtube superlattice microstructure embedded in the metallic host. The design strategy rigorously starts from the theoretical analysis on the spectral representation of effective permittivity in quasistatic conditions for the Hashin-Shtrikman coated-cylinder microstructure, then improves in full-wave conditions for the nanoscale airtube superlattice microstructure. Through the computational simulations, the correctness and robustness of the strategy are verified and the broadband epsilon-near-zero property of the designed metasurface is demonstrated. Furthermore, the physical mechanism behind the broadband epsilon-near-zero property, including the potential application in broadband deep subwavelength electromagnetic wave tunneling, is also straightforwardly revealed.
