In the 21st century, ultra-precision machining has been extensively applied in the field of optics, such as spherical/aspherical lenses, multifocal lenses, Fresnel lenses, polygonal mirrors, pyramidal arrays, microstructure arrays, v-grooves [15], [176], [177]. Due to the preciousness of ...
An iterative Fourier transform algorithm method based on Fresnel diffraction is used to calculate the phase profile of a multifocal metalens at λ = 541, 621, and 750 nm (Huang et al., 2020); the simulated full width at half maximum (FWHM) of focal spots showed that the metalens designed...
