Honeycomb lattice phononic crystal

WebPhononic crystals (PCs) are artificial periodic composites designed to exhibit phononic band gaps and they have been quite studied 1 - 14. There are no mechanical (elastic or acoustic) propagating waves in phononic band gaps, only evanescent waves. These band gaps are created by the periodically mismatch between the constituent materials. Web11 apr. 2024 · In this Perspective, we review recent progress in antichiral topological photonic states in magnetic photonic systems for the basic concepts, properties, and applications. Additionally, we provide an outlook for emerging frontier topics, promising opportunities, fundamental challenges, and potential applications for antichiral magnetic ...
