Fields inside the source are the 'total' field (i.e. It can be noted that the edge of the TFSF source is visible in the plots as abrupt changes in the image color. The following figures show \( |E|^2 \) in the XY, XZ and YZ planes through the center of the particle at a wavelength point closest to the 'target wavelength' specified in the script. Frequency domain field monitors directly measure the local field enhancement. Interactions of the electromagnetic field with the nanoparticle can create strong field enhancements at the particle surface. The associated script file can be used to plot the representative results shown below. Results can be explored manually by right-clicking the monitors or analysis group and selecting the quantity of interest. Open the simulation file and click the "Run" button.
