Leonardo A. Ambrosio received the B.Sc., M.Sc. and the Ph.D. degrees in Electrical Engineering from University of Campinas, School of Electrical and Computer Engineering, Campinas, Brazil, in 2002, 2005 and 2009, respectively. Between 2009 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. His research interests include Photonics, light-scattering problems for optical trapping and manipulation, metamaterials and plasmonics for optical nano-circuits and microstructures light fields and modelling of non-diffracting beams envisioning applications in biomedical optics, telecommnications and atom guiding.

Several national and international research groups have been involded with theoretical, numerical and experimental analysis on nondiffracting waves in acoustics, microwaves and optics, biomedical optics, medicine and even in particle physics and gravitational waves. In particular, we have become specialized in specific classes of nondiffracting beams since the first theoretical and practi…
Non-diffracting waves have been, during the last decade, objects of intense analysis and investigation by several research groups worldwide, with plenty of potential applications being envisioned such as in acoustics, microwaves and optics, mechanics, geophysics, biomedical optics, medicine and even in elementary particle physics and gravitational waves. In view of the most recent theoret…
This proposal of scientific initiation aims to promote theoretical and numerical studies about the generalization of Snell's law in plane and spherical dielectric interfaces when in presence of a metasurface. To achieve that goal, this project includes activities to reinforce fundamental concepts of electromagnetism, to understand the origin of Snell's law according to Fermat's principle …
This document presents the proposal for a research based on a seminal study of plasmonic metamaterials. The main goal of this study is to understand the phenomenon of optical cloaking from plasmonic layers over dielectric spherical particles whose dimensions are much smaller than the wavelength. To do so, the twelve-month-project has been organized as follows: (I) revision of fundamental …
This proposal aims to provide a natural and challenging extension for the student in relation to the concepts developed in his first FAPESP scientific research. To do so, it presents a theoretical study about a specific class of non-diffracting beams which is highly promising in optical trapping: the so-called continuous and vector frozen waves (CVFWs). It is an extension of the concepts …
