Honeycomb-lattice Minnaert bubbles

Understand

The ability to manipulate the propagation of waves on subwavelength scales is important for many different physical applications.

• In this paper, we consider a honeycomb lattice of subwavelength resonators and prove, for the first time, the existence of a Dirac dispersion cone at subwavelength scales.
• As shown in [H.
• Ammari et al., A high-frequency homogenization approach near the Dirac points in bubbly honeycomb crystals, arXiv:1812.06178], near the Dirac points, honeycomb crystals of subwavelength resonators has a great potential to be used as near-zero materials.
