I'm hoping someone can help me with an issue I'm having in COMSOL. I'm trying to model a 160um by 13um long gold rod in order to get extinction spectra so I can figure out where its peak is and match that up with results from a spectrometer for an actual gold rod of that size.
I'm running it in scattered field in 2D, using the RF Module and Frequency Domain study. I obtain spectra by running a surface integration on the results on emw.normEfar^2 but so far, with all the reflections I'm getting the output is useless. I've tinkered a bit with scale and found that if I run it all as nm the result is fine, or if I run models that are 1.6um by 0.13um even that I get appropriate results. I've attached an image of the field plot and hopefully someone can either point me in the right direction for modelling things at this scale or give me some tips on what to look at.
