We are trying to simulate the extinction spectra of 90% Ag and 10% Au alloy in COMSOL. Can anyone help us tell which module and equation can be used to simulate extinction spectra in COMSOL? Can we obtain extinction spectra of alloy using Mieplots?
Kaja Sravani In COMSOL, extinction spectra of nanoparticles may be simulated by simulating the nanoparticles' electromagnetic response to incoming light. You may accomplish this by utilizing the Electromagnetic Waves module, which allows you to solve Maxwell's equations in multiple frequency regimes.
The Mie scattering solution may be used to simulate extinction spectra. The extinction cross section, which is the total amount of energy absorbed or dispersed by the nanoparticle in a certain direction, is calculated using this solution. The extinction cross section may be used to compute the nanoparticles' extinction spectra.
The Mie scattering solution in COMSOL may be used by describing the shape of the nanoparticle, specifying the material parameters, and configuring the relevant boundary conditions. After running the simulation, you may obtain the extinction cross section and use it to compute the extinction spectra.
In terms of software, the Mieplot tool in COMSOL may be used to show the extinction spectra. The Mieplot tool provides a graphical user interface for displaying the results of Mie scattering simulations, such as nanoparticle extinction spectra.
It should be noted that the accuracy of the simulation results is determined on the quality of the material characteristics and the simulation setup. If possible, check the simulation results against experimental data.
