This file serves as documentation for the other files in this folder 30to1um_Au_exp_cond.hfss : This is the HFSS model used to generate figure 1b. The conductivity of the gold has been changed from the default to reflect experimentally measured data. circletaper5_PerCond.hfss : This model has a geometry that was exported from the mask data for the 5 um tapered devices. The metal has been changed from gold to a perfect conductor and the substrate has been removed. This allows a simulation with effectively no loss, where the field concentration effects can be isolated from attenuation effects. Other files contain data or source files for figures as labelled in the filename. Data collected in years 2016 & 2017
