2025年11月11日，由欧洲杯直播开展的品牌系列讲座【南高师·格物讲堂】邀请到了法国国家科学研究中心Badreddine Assouar教授，于行健楼437作了题为“基于超结构调控声场”的学术报告。讲座由欧洲杯直播朱兴凤教授主持，欧洲杯直播 相关领域的教师，部分研究生和本科生参加了本次报告会。

在本次报告中，Assouar教授首先概述了声学与弹性超构材料领域的一些最新研究进展，重点介绍了这些人工结构材料如何用于调控声波。通过利用特殊共振、波干涉与杂化以及对称性破缺等物理机制，超构材料实现了在紧凑轻质平台上的波束操控、聚焦、隔离与吸声等功能。

随后，Assouar教授探讨了声学全息术概念的最新进展，包括基于反射和透射效应的研究。他展示了一些关于复用全息和加密全息的研究成果及其潜在应用。

报告完毕之后，Assouar教授与现场的老师和学生，就报告中的一些具体内容进行了深入交流。

Assouar教授简介：

Badreddine Assouar received his PhD degree in Materials Physics from Nancy University in France in 2001. In 2002, he became a Research Scientist at “Centre National de la Recherche Scientifique (CNRS)” in France. He obtained his habilitation to supervise research (HDR) in 2007 and became a Research Professor. In 2010, he joined Georgia Institute of Technology in USA as visiting Professor, where he spent 2 years, developing researches on metamaterials. He afterwards founded the “Acoustics Metamaterials and Phononics” group at the University of Lorraine where he is developing researches on acoustic/elastic metamaterials, metasurfaces, phononics and wave physics. He is currently a Director of Research at the CNRS. He is author or co-author of more than 150 international peer reviewed publications, in leading international journals including, Nature Communications, Nature Review Materials, Science Advances, Advanced Functional Materials, Physical Review Applied, Physical Review B, and more than 50 invited talks and keynotes over the world. This has led to highly recognition of his works and achievements over the past 15 years, as indicated by the high citations rate his works has collected (8500 citations, and h-index of 51). Prof. Assouar is serving as an Associate Editor with Physical Review Applied since 2019. He has chaired and organized many international conferences such as International Congress on Ultrasonics and Phononics conference.
