| Sumario: | This thesis presents a unified study of the theory involved in optical trapping, which aims to be a comprehensive guide for students and / or teachers who in the future want or need to enter the area of optical tweezers. Starting with a historical introduction, we proceeded to the study of electromagnetic fields and a search for solutions to Maxwell's equations, which naturally led us to the definition of electric and magnetic transverse modes based on the vector spherical harmonics that are fundamental for the study of particle scattering and allow this phenomenon to be studied more precisely with the use of the T matrix, which is used by a large number of scientists from the optical entrapment and manipulation community. With the help of the MATLAB software, particle trapping was simulated, the T matrix and various parameters of interest were calculated with different types of lasers, numerical apertures, among others, thus giving a comprehensive and unified study of the forces and other variables involved in optical tweezers. Finally, the inclusion of the Mathieu beams to the \ Optical Tweezers Toolbox " developed by the optical micromanipulation group of the University of Queensland is presented, which will allow to study in depth the forces in the optical traps generated by this type of beams, something not reported so far. |
