All-dielectric metasurfaces with full phase control by using only electric response

This thesis studies different approaches for designing transmitting metasurfaces. The goal was to develop a novel approach that enables full phase control of the transmitted field. The suggested method utilizes metasurfaces at oblique incidence, which enables excitation of additional resonating modes. Spectrally overlapped electric eigenmodes give 2pi phase coverage with high transmission amplitude. This approach is used in order to create a transmitarray, which refracts incident light at a desired angle. The results show that the suggested approach can be used to design robust and low-loss metasurfaces
