a Calculated ECD values of the device under different δ conditions. b Far-field radiation polarization patterns of the device for δ values of −280, −140, 0, 140, and 280 nm. c and d Spectral dependence of the LCP and RCP thermal emission on the output angle along x (c) and y (d) directions for δ = 280 nm. The color amplitude indicates the emissivity. e Real part of the Ez for the LCP and RCP emissions at 0° output for δ = 280 nm. f Angular distribution of the emissivity for LCP emission at different wavelengths with respect to the y direction for δ = 280 nm.
