Application of COMSOL Multiphysics for Nanosphere Dimer

open access: yesDEStech Transactions on Computer Science and Engineering, 2018
A simple nanosphere dimer system was constructed based on the wave optics module in COMSOL Multiphysics to verify their hot spots effect. By mapping their electric field distributions, we found that as the nanogap decreases or the nanosphere radius increases in a way, the field enhancement of the dimer goes up. In addition, the resonant peak along with

Visualizing acoustic levitation using COMSOL Multiphysics

open access: yes, 2023
We present a new virtual laboratory developed with COMSOL Multiphysics for the simulation of an acoustic levitator. Our computer application simulates the acoustic pressure field and its interaction with a set of particles. Students can interact with the system by having the possibility of changing the frequency and distance parameters between ...
