報告題目：Some Aspects on Ultrafast and Near-Field Radiative Transfer
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 addressesemerging 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, I will introduce some 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 my research group at Rutgers. First, I will talk about our pioneering contributions in ultrafast laser radiation propagation modeling and experimentation, addressing biomedical imaging and optical breakdown. Then I will demonstrate our experiment on nanofabrication in combination with use of AFM tip. In the same time, we will re-exam the conservation laws in the modeling of radiative transfer. Our 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. We will explore nanoscale and molecule level sensing and on-chip dynamic temperature monitoring using WGM micro-sensors.
Dr. Guo 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 Poly-technic University (now NYU-Tandon School of Engineering), where he completed his Ph.D. in Mechanical Engineering in the same time period. 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 has supervised 16 PhD and 17 Master students and mentored 14 postdoctoral/visiting scholars. He received research funds from the NSF, NASA/NJSGC, USDA, ASEE/DOD, MTF, NIH, NJ Nanotechnology Consortium, Charles and Johanna Busch Memorial Funds, NNSFC, JSPS, and other sources. He also received a teaching award from Rutgers Vice President Office for Undergraduate Education in 2002. He is the author or co-author of over 130 articles/editorials in archival journals, with a similar number of conference publications. He is the Editor-in-Chief for Journal of Enhanced Heat Transfer, 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 and for Frontiers in Energy. Dr. Guo is an elected Fellow of ASME. He was the K-18 technical committee Chair of Heat Transfer Division in ASME during 2009-2015. He was the Technical Program Chair for the 6th International Symposium on Advances in Computational Heat Transfer (CHT-15). He was a conference Co-Chair for 2011, 2013, and 2015 International Workshops on Heat Transfer Advances for Energy Conservation and Pollution Control. Among many distinctions, he was awarded a JSPS Invitation Fellowship, a K.C. Wong Education Foundation Fellowship, and Rutgers the Board of Trustee’s Award for Excellence in Research.
