Non-diffracting waves: from theoretical derivation to practical applications
報 告 人：
Professor Leonardo André Ambrosio, University of S?o Paulo, Brazil
In this talk, firstly, a short introduction of the University of S?o Paulo and Department of Electrical and Computer Engineering will be given, which is followed by a brief overview of recent activities/highlights in my research group. Then, starting with a general mathematical approach, a rigorous definition of a non-diffracting wave is given, and we then derive solutions of the scalar wave equation for the well known Gaussian beams, Bessel beams andX-shapedpulses. Some practical examples will also be presented.
Leonardo A. Ambrosio received the B.Sc., M.Sc. and the Ph.D. degree in Electrical Engineering from University of Campinas, School of Electrical and Computer Engineering, Campinas, Brazil, in 2002, 2005 and 2009, respectively. Between2009 and 2013 he was a postdoctoral Fellow with the Department of Microwaves and Optics at the School of Electrical and Computer Engineering, University of Campinas (Unicamp), and developed part of his research at the University of Pennsylvania, Philadelphia,USA. He is now Professor Doctor at the University of S?o Paulo, in Brazil, the most prestigious and renowned university in Brazil and South America, with the Department of Electrical and Computer Engineering of the S?o Carlos School of Engineering. His research interests include Photonics, light-scattering problems for optical trapping and manipulation, metamaterials and plasmonics for optical nano-circuits and microstructured light fields and modeling of non-diffracting beams envisioning applications in biomedical optics, telecommunications and atom guiding.
