Soret Fishnet Metalens Antenna [PDF]
Scientific Reports, 2015 Abstract At the expense of frequency narrowing, binary amplitude-only diffractive optical elements emulate refractive lenses without the need of large profiles. Unfortunately, they also present larger Fresnel reflection loss than conventional lenses.
