The data in SiC_sim_results are used to plot the figures relevant to the SiC case in the paper.
The data are in .mat format, which can be opened by Matlab. An example Matlab script for opening the data is saved in the folder and named “example_read.m”.

The data structure is as following:
- SiCxxxx is the structure containing the simulation data for SiC using an antenna of length xxxx nm.
SiCxxxx.tt is the time axes
SiCxxxx.ff is the frequency axes
SiCxxxx.Ex is an array representing the x-component of the electric field at the time and frequency points described by the .tt and .ff arrays.
SiCxxxx.Exnor is as the above but normalised.
SiCxxxx.Ez is an array representing the z-component of the electric field at the time and frequency points described by the .tt and .ff arrays.
SiCxxxx.Eznor is as the above but normalised.

Resonances:
sic_resonances = [50, 50, 40.05, 35.03, 31.86, 30.35, 29.77, 29.43, 29.18, 29.1, 29.01];
