Abstract

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 practical demonstrations, at the scale of meters, of the so-called Frozen Waves (FWs) and Diffraction-Attenuation Resistant Beams (DARBs), both based on suitable discrete or continuous superpositions of scalar or vector Bessel beams for achieving an unprecedent control over the effects of diffraction and absorption. Recently, the proponent has initiated, jointly with national and international researchers, the incorporation of infinite eneregy and discrete scalar and vector (circularly symmetric) FWs and DARBs into the field of optical trapping, based on theoretical formalisms associated with the electromagnetic scattering by spherical particles. Some important features were analyzed, e.g. the radiation pressure cross sections. Because of the growing interest in such light waves, this project aims to make progress on reliable and accurate theoretical and numerical studies involving the space-temporal modeling on such microstructured beams within the context of the generalized Lorenz-Mie theory. During the validity of the project, it is intended to extend previous research so as to also encompass not only discrete, but also continuous and finite-energy vector FWs and DARBs. Besides, it is of actual interest to consider other degrees of freedom such as optical torque and orbital angular momentum, which have their value in a variety of applications in optical trapping and in atom guiding. This proposal, standing at the frontier of knowledge of such an important research area, has a semester-planned schedule, and shall be developed in partnership with important names and research groups worldwide.
