Abstract

We show that symmetry-breaking design principles enable metasurfaces fed from guided modes that radiate with pointwise specification of amplitude, phase, and polarization. We demonstrate this platform for both optical frequency and radiofrequency devices, including beam-steering, polarization-switchable operation, and multiple-input multiple-output functionality.
