Dear MEEP users: I am new to the MEEP simulation environment and am trying to simulate the e-field enhancement localized within a 20nm thick Si layer when a period array of cylindrical Gold nano-posts are placed on its surface.
I am trying to set up a simulation which shows how the e-field (Ex+Ey+Ez) magnitude in the thin metal layer beneath the posts varies at different incident (wavelengths 690nm through 800nm linearly polarized along the z-axis). The posts are periodic in the x and y directions. The geometry is contained within a large air subdomain, the real and imaginary values of the relative permitivity for the Au post change at each wavelength, the entire geometry is contained within a large air subdomain. The period of the gold posts would start at 200nm with the post diameter= 1/3 the period. I am interested in looking at periods 200 and 400nm. I have been trying to work with some existing examples but have not had much luck yet. I am very much a beginner when it comes to programming (I have some experience using Comsol Multiphysics). Any help, suggestions on how i could set up the code for the simulation would be much appreciated. Thank you!! _______________________________________________ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
