Comparison of rejection ratio between L-band and M-band optical measurements and the RCWA model. Left: measured rejection ratio in five different filters for AGPM-L9 and its remastered versions. AGPM-L9r and AGPM-L9r2 were etched 400 nm and 780 nm deeper than the original AGPM-L9, respectively. Right: possible parameter solutions (marked with crosses) for each optimization, overlaid on predicted coronagraphic performance from RCWA simulations (white lines) with and wavelength region between 3.54.0 μm.
