Abstract
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 theoretical and experimental demonstrations of Frozen Waves (FW) and of the so-called DARBs (Diffraction-Attenuation Resistant Beams), which are formed by suitable superposition of Bessel beams for achieving beams extremally resistant to diffraction and absorption, there comes a natural tendency of fiding appropriate descriptions and solutions, besides potential applications, for these solutions of the scalar (or vector) wave equation at the millimeter and micrometer scales, such as in the current research areas of the main researcher, viz., optical trapping and manipulation. The project here proposed thus aims to transform into theoretical and numerical reality the use of FWs, DARBs and other new classes of non-diffracting waves in electromagnetic propagating and scattering problems, taking advantage of their particular and significant properties of longitudinal intensity pattern modulation in addition to their well-known (self-reconstruction and diffraction-resistance) characteristics. The schedule, which has been split into three-month stages, predicts periods of theoretical studies and numerical treatments in order to put such beams as alternative and efficient electromagnetic fields in a variety of electromagnetic problems at the millimeter and micrometer scales.
