Abstract

The spatial modelling of optical beams is a strong theoretical and experimental research field that, among others aims, seeks to minimize the physical effects of diffraction and attenuation, it is used in various applications; such as, in medicine, images, optical tweezers, optical guidance of atoms, remote sensing, free space optical systems, etc.This research project focuses in the study and the development, mostly through theory and simulations, of techniques to the spatial modelling of electromagnetic beams in millimeter and microwave wavebands. Furthermore, it will be analyzed possible generating antennas of the wavebands obtained theoretically, as well as medical applications through the hyperthermic effect. Therefore, it will be showed solutions for Maxwell's equations that supports the initial thesis of Bessel beam and Frozen Waves generation in GHz and THz frequency bands. Then, it will be performed beams simulations and antenna proposals in specific software. After all, the hyperthermic effect generated by such beams will be analyzed through simulations and/or experiments.The work will be developed over two years in the Faculty of Electrical Engineering and Computing of Unicamp with the collaboration of some important nation and international research centres, which the tenderers have close cooperation, namely: Department of Electrical and Computer Engineering, University of Toronto (Canada), Department of Electrical and Computer Engineering, Virginia Polytechnic Institute (USA) and the Institute of Applied Physics "Nello Carrara" (Italy).This work proposal is located within an important research area and will be detailed in the following sections.
