All-dielectric nanophotonics has become one of the most active fields ofresearch in modern optics, largely due to the opportunities offered by thesimultaneous resonant control of electric and magnetic components of light atthe nanoscale. In this rapidly evolving scenario, the possibility to designartificial Huygens sources by overlapping electric and magnetic resonances hasestablished a new paradigm in flat optics, bringing devices closer to efficientwavefront shaping with a direct phase engineering at the level of theindividual meta-atoms. However, their efficiency is fundamentally limited bythe near field coupling between the constituents of the metalattice. In thiswork, we challenge this well-conceived notion and propose an alternativeconcept to achieve phase control and full transmission in metasurfaces, basedon the unusual properties of the nonradiating sources known as Hybrid Anapoles(HAs). We analyze theoretically an array of such sources and demonstrate thatHAs are characterized by a negligible coupling with their neighbors. Therefore,in contrast to Huygens particles, the proposed sources can operate asindividual meta-atoms even in highly compact designs, becoming robust againststrong disorder and preserving its characteristics when deposited on dielectricsubstrates. Remarkably, the phase of the transmitted wave can be modulated withnegligible reflection. To illustrate the capabilities of our platform, we alsoutilize a disordered HA array to implement a controlled phase modulation to anultrafast gaussian pulse. The results of our study represent a departure fromthe currently established designs and open an avenue towards the realization ofnew devices for flat optics with unprecedented efficiency.
