Scatter-free perfect reflection in multichannel monolithic high-contrast gratings: direct--indirect Fourier-harmonic interference and dimensionality of the solution set

Monolithic high-contrast gratings (MHCGs) can exhibit scatter-free perfect reflection despite open higher-order substrate diffraction channels, but the underlying mechanism has not been fully clarified. Using a Fourier-harmonic description, we show that all open higher-order channels in the high-index substrate can be...
