     Masud Mansuripur教授,美國Rep. Prog. Phys.期刊主編,現任職于美國亞利桑那大學,光學科學學院。主要研究方向包括:光學數據記錄、磁光學、光學材料制備與表征、薄膜光學、光衍射理論、大分子數據存儲,以及與輻射壓力和光子動量相關的科學問題。

       Abstract: The rays of light carry energy as well as linear momentum and angular momentum. The latter properties are exploited in solar sails, optical tweezers, and micro/nano opto-mechanical motors and actuators. A fundamental characteristic of photons, their momentum inside material media, has been the subject of debate and controversy for more than a century. The so-called Abraham-Minkowski controversy involves theoretical arguments in conjunction with experimental tests to determine whether the vacuum photon momentum must be divided or multiplied by the refractive index of the host medium. Also, momentum conservation is intimately tied to the force law that specifies the rate of exchange of electromagnetic and mechanical momenta between light and matter. In this presentation, I will discuss the foundational postulates of the Maxwell-Lorentz theory of electrodynamics with the goal of clarifying the prevailing ambiguities and resolving the reigning controversies.

 

Speaker: Masud Mansuripur (PhD, 1981, Electrical Engineering, Stanford University) is Professor and Chair of Optical Data Storage at the College of Optical Sciences of the University of Arizona in Tucson. He is the author of "Introduction to Information Theory" (Prentice-Hall, 1987), "The Physical Principles of Magneto-Optical Recording" (Cambridge University Press, 1995), "Classical Optics and its Applications" (Cambridge University Press, 2002, second edition 2009, Japanese translation 2006 and 2012), and "Field, Force, Energy and Momentum in Classical Electrodynamics" (Bentham e-books 2011, second edition 2017). A Fellow of OSA and SPIE, he is the author or co-author of over 250 technical papers in the areas of optical data recording, magneto-optics, optical materials fabrication and characterization, thin film optics, diffraction theory, macromolecular data storage, and problems associated with radiation pressure and photon momentum.
