Collection description
The Ph.D. Thesis discusses the use of plasmonic structures to induce optical propulsion, which has significant novelty and impact in various fields, including aerospace and biological sectors. Starting from the state-of-art and the physics of the surface plasmonic, the article highlights the limitations of already published plasmonic structures and presents an optimized plasmonic structure that overcomes those limitations. Finite element simulations have been carried out both to study the influence of each geometrical parameter and for an estimate of the dynamics induced on gold nanoparticles. After analyzing all the results obtained from the simulation process, the system was fabricated and initial sample characterization tests were carried out. In addition, we discuss through the study of the phenomenon of orbital spin coupling, an additional effect for manipulating nanoparticle trajectories via the spin momentum of the evanescent wave.
