题 目：The Algorithm and Experimental Design of Electromagnetic Wave Light Pressure of Membrane
Based on the classical electromagnetic wave theory, the report will introduce the results of particle light pressure calculation of the Mie scattering model and the Gaussian beam waist model. And discuss the problems encountered in the classical electromagnetic wave light pressure prediction method extended to the large size Membrane model. The key point is recently developed wavefront surface curvature introduced into ray model and solving the bottleneck problem of light scattering fluid measurement of large irregular objects. The research results show that the theoretical model is simple, the calculation is fast, and the results are accurate.
Finally, the latest advances in the measurement of fluids (droplets, bubbles, etc.) by several optical measurement techniques will be discussed, as well as how to construct an optical measurement platform to determine the light pressure experienced by the Membrane.
Dr. Kuanfang Ren is graduated from the Physics Department of Shaanxi Normal University and received a master's degree in Radio Physics from Xidian University. He went to France to study abroad and received a Ph.D. in physics from Rouen University. Since 2015, he has been employed as a first-level professor at the University of Rouen, France.
Up to now, Professor Ren Kuanfang has published more than 90 papers in international journals, published more than 100 papers in international conferences, and developed six scientific and software software. He has proposed and completed the elliptical Gaussian wave theory description formula, mathematical proof and numerical calculation method. He also has proposed and completed the theoretical and numerical calculation of the plane wave expansion of the cylindrical beam on a shaped beam. The recently proposed "wave ray theory model" provides a powerful tool for studying the interaction between irregular targets and waves. He has hosted and participated in many scientific research projects in the European Community and France. He is currently chairing the “Advanced Optical Measurement Technology for Complex Particles” project of the French Research Institute. The participating organizations include four important research institutes of the French National Academy of Sciences (CNRS).
