Optical Forces In Optical Tweezers

This open source project by Antonio Alvaro Ranha Neves is for Mathematica implementations of optical forces in optical tweezers. It relies on the generalized Lorenz-Mie theory (GLMT) and the highly focused beam described by angular spectrum representation.

This is a simple code that implements a generalized Lorenz-Mie theory (GLMT) solver for electromagnetic scattering from spherically-symmetric bodies.



Validating the method of fundamental solutions for computing the total scattering cross-section of a sphere. The notebook is intended for validating the model presented in the paper entitled, "Modeling broadband cloaking using 3D nano-assembled plasmonic meta structures," by M. Khan, S. Ghosh, R. Baxter, and A. D. Kim (2020).
