I have been working on the small-scale metalens-field propagation<\/a> app using 2022 R1.1 version 8.27.2963 and having a few issues.<\/p>\n

First, I noticed that the file “unit_cell.fsp” will not open, giving me an error stating “Error reading file”. Why is this the case, and what is the significance of this file?<\/p>\n

Second, I noticed that the “unit_cell_fdtd.fsp” file has optimization\/sweep variables called “height” and “radius”. When I try to edit these sweep variables and try to run “unit_cell_fdtd.lsf”, the sweep variables will reset to what they were before. Where can I edit this so that I can change the height and radii of the sweep?<\/p>\n

 <\/p>\n

Lastly, where does the index of refraction for the pillars come from? I have a set index of refraction I would like to use for my material, but it looks like the code references a Matlab data file for the index of refraction of the material. Why is this?<\/p>\n","protected":false},"template":"","class_list":["post-352405","topic","type-topic","status-closed","hentry","topic-tag-fdtd","topic-tag-metalens-1","topic-tag-phasemetalens-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
