Abstract

This research project focuses on the study of non-diffracting pulses in dispersive absorbing media and will be developed in collaboration with the group of photonics of Prof. Mohammad Mojahedi, at the Department of Electrical and Computer Engineering, University of Toronto, Canada (http://www.mogroup.utoronto.ca/). More specifically, after a careful contextualization of the different theories on pulses resistant to the phenomenon of diffraction and attenuation, the research will be focused on: 1) improvement of the existing methodologies concerning the Airy-Bessel pulses, in order to describe more realistic situations connected to the processes of experimental generation and 2) a description of the consequences of attenuation on the existing models and the attempt to develop a method for obtaining pulses resistant (by certain distances) to the three simultaneous effects: diffraction, dispersion and attenuation. This could be seen as a generalization of the concept of non-diffracting wave. (AU)
