报告内容:Optical and acoustic sensing technologies are of great importance in many areas such as biomedical and industrial applications as well as national defense. While in last two decades remarkable progress has been achieved in the development of new materials and sensors, there is still an increasing demand on breakthrough technologies and new functional materials that can revolutionize next generation optical and acoustic devices. In this talk, I will introduce my recent research efforts on the development of novel optical and acoustic man-made materials and sensing systems, aiming to address fundamental challenges and urgent needs for sonar and acoustic communication systems, ultrasonic medical instruments, sensing systems applied in high energy systems and robotic sensors. First, I will show how to use high-refractive index acoustic metamaterials to manipulate acoustic waves at subwavelength scales. Further, the acoustic metamaterials are integrated with optical fiber sensors, which enable a novel sensing paradigm that can overcome the fundamental detection limit of conventional acoustic sensors. Second, I will discuss the unique optical, mechanical and acoustic properties of nanophotonic materials (e.g., photonic crystals) which can be exploited in the development of next generation ultrasonic transducers. Further, I will show how the application of nanophotonic materials and structures can help greatly enhance the performance of optical sensors applied in complex environments and high energy systems (e.g., combustors, automobile/aircraft engines). Finally, I will introduce our recent progress on biomimetic materials and transducers applied for autonomous robotic systems (e.g., unmanned vehicles and UAVs).

报告人简介:陈永耀,现任美国马里兰大学(University of Maryland)助理研究教授。研究课题涉及光电和声学传感器、电磁波和声学人工材料、仿生传感器等交叉学科领域。近4年参与和共同主持美国国家自然科学基金(NSF)两项,美国海军研究 (ONR) 基金一项,美国空军科学研究 (AFOSR) 基金一项。这些相关的研究成果在国防技术、高能系统(例如舰艇和航空发动机系统)、工业应用、医疗应用、以及机器人等多个领域具有极其重要的意义和广泛的应用前景。到目前为止,在传感器以及声/光人工材料等领域取得多项成果,在多个国际知名杂志,包括Nature Communications、Applied Physics Letters、Optics Express、等发表论文16篇,并且被Nature Review Materials、Nature Communications、Physics Review Letters、Applied Physics Letters等高水平杂志多次引用。由于在声-光混合型传感器以及人工材料领域取得了原创性突破,于2015年被美国声学学会邀请在其年会 (Annual Meeting of the Acoustical Society of America) 做相关课题的专题研究报告。相关研究工作被Phys.org、Yahoo News 以及International Defense, Security & Technology 等多家国际知名媒体所报导。
