Abstract

Huygens' meta-atoms are key elements for obtaining full power transmission through metasurfaces with full control over the transmission phase. Conventional Huygens' meta-atoms use spectrally overlapped magnetic and electric resonances. However, realization of this approach is challenging due to several drawbacks including different bandwidth and mutual coupling of the resonances. In this talk, we study metasurfaces comprised of elementary electric dipoles and discuss ways of obtaining the functionality of Huygens' meta-atoms without the use of magnetic response. We show that this approach is beneficial considering frequency bandwidth and the inclusions size. Finally, we present a design of an optical transmitarray that bends normally incident waves at 45° angle.
