报告内容:

Light, a form of Electromagnetic Radiation, has a dual nature – wave and particle properties. Wave propagation, which builds the foundation of optics and evanescent phenomenon that addresses emerging applications in such as nanotech, is described by Maxwell’s equations. While transport in particle form is governed by the equation of radiative transfer (ERT). Radiative transfer is an important mode of heat transfer in thermal and energy systems.

In this talk, he will introduce the cutting-edge research and developments on both aspects of radiation transport from large-scale to nanoscale, and from steady state to ultrafast regime performed by his research group at Rutgers. First, he will talk about their pioneering contributions in ultrafast laser radiation propagation modeling and experimentation, addressing biomedical imaging and optical breakdown. Then he will demonstrate their experiment on nanofabrication in combination with use of AFM tip. Their recent discovery on the conservation of asymmetric factor revealed the major discrepancies existing among different radiative transfer modeling methodologies. Finally, whispering-gallery mode (WGM) optical resonance in near-field has attracted increasing attention in MEMS/NEMS devices. They will explore nanoscale and molecule level sensing and on-chip dynamic temperature monitoring using WGM micro-sensors.

报告人简介:

Dr. Guo Zhixiong is a full Professor of Mechanical and Aerospace Engineering at Rutgers University-New Brunswick, NJ, USA. He received his B.S., M.S., and Doctorate, all in Engineering Physics, from Tsinghua University, Beijing. Then he left China and worked as a Research Fellow in KAIST, South Korea, and a Research Associate (Assistant Professor) in Tohoku University, Japan. From 1999 to 2001, he worked as a research staff member in Polytechnic University (now NYU-Tandon School of Engineering). He joined the faculty at Rutgers in July 2001.

  

He is a recognized expert in heat transfer, with notable expertise in radiation transport and laser applications.He is a pioneer in ultrafast laser radiation transport modeling and applications. He explored plasma-mediated ablation and developed it successfully to tissue grafting and decontamination. He conducted leading research on near-field radiation, addressing emerging technological applications such as MEMS/NEMS sensors, ultrafine measurement, and biological sensing at the molecular level.

  

He is a Managing Editor for journal Heat Transfer Research, an Associate Editor for Journal of Heat Transfer, and an editorial board member for Applied Thermal Engineering. Dr. Guo is an elected Fellow of ASME.
