Abstract
It is well known that electromagnetic waves can be superimposed and thus create interference effects. By applying this fact one can focus light by superimposing a specific combination of electromagnetic wave fronts. Using numerical simulations, I demonstrated a possibility of such focusing through a random medium. These simulations were done in COMSOL Multiphysics in conjunction with Matlab to launch certain combinations of plane waves through a substrate with metallic scatterers placed on top of it. I have shown that one can focus light in a specific place, and by tuning the phases of the waves one can translate the focused light across the sample. One application for this setup is scanning biological molecules that are attached to metallic nanoparticles without using moving parts.
