Comparison of optical transmission spectrum of NHAs with the diameters of a 175 nm before annealing by simulation (black line symbol) and measurement (red line symbol), and (same sample shrunk to) 150 nm after annealing by simulation (green line symbol) and measurement (blue line symbol); b 235 nm before annealing by simulation (black line symbol) and measurement (red line symbol), and (same sample shrunk to) 209 nm after annealing by simulation (green line symbol) and measurement (blue line symbol)
