Calculating near field distribution of a FESEM image of nanoparticles in FDTD


#1

Hey aalam…Could you please help me to calculate near field distribution of a FESEM image of nanoparticles by importing it into the software? I know how to import the image, but after that I don’t know what to do.
I want to compare calculated results with analytical modelling done in MATLAB.

Hi. Once you have imported the nanoparticles into FDTD, all you need to do is to define the simulation volume, add a source (plane wave for periodic structure, TFSF for non-periodic case), add a DFT monitor to look at the electric field profile or/and add a power absorption analysis group to look at the absorbed power in the nanoparticles. Once the particles are imported, the rest of the task should not be much different from any of these examples,
