2023年3月17日晚八点，iCANX Talks 第135期将在iCANX平台上线！本期我们邀请到美国国家发明家科学院院士Andrea Alù教授进行分享！更多精彩，敬请期待！

The field of metamaterials, artificial materials engineered at the nanoscale, has been rapidly evolving in the past two decades, demonstrating extreme wave phenomena and unprecedented control over wave propagation. In this talk, I discuss recent developments in this field of research, with an emphasis on the role of symmetries in establishing emerging optical and acoustic responses for metamaterials based on otherwise simple constituents. Geometrical rotations, suitably tailored perturbations, and broken time reversal symmetry can be carefully engaged to tailor waves in robust and efficient ways, control their propagation, break Lorentz reciprocity and enable topological order and phase transitions. I will discuss the underlying physical principles that span over many wave platforms, and their impact on practical technologies, from imaging, energy and sensing to computing and communications. 

超材料为纳米尺度下人工合成的具有特殊物理特性的人造材料，它在过去二十年间得到迅速发展，展现了其对极端波现象与波传播前所未有的调控。这个报告将讨论超材料领域的最新进展，重点探讨对称性操作对声波和光波超材料的独特作用。这些对称性操作包括几何旋转对称性操控、按需对称性微扰调控、时间反演对称性操控等；通过对称性调控，可显著提高波传播控制的鲁棒性与高效性，打破波传播的互易性，以及控制系统的拓扑序和相变。该报告从不同波动超材料系统的基础物理出发，阐述其在成像、能源、传感、计算、通讯等诸多领域中的影响和应用。
