Query: Ultrathin wave plates based on bi-resonant silicon Huygens' metasurfaces   An all-dielectric Huygens metasurface supporting electric and magnetic
resonances is a promising platform for a variety of optical applications that
require a combination of extremely high transmission and broad-range control of
the phase of the transmitted light. A highly efficient wave plate is one
example of such an application. In combination with high spectral selectivity
and strong optical energy concentration, such phase plates are desirable for
precision sensing and high efficiency nonlinear optics. We propose a novel
approach to realizing such ultra-thin optical plates: an anisotropic
Fano-resonant optical metasurface (AFROM) employing the combination of a
spectrally sharp electric and a relatively broadband magnetic resonance. The
phase shift coverage approaching 2{\pi} is achieved through judicious choice of
the geometric parameters of a complex unit cell. A new methodology based on
eigenvalue simulations of leaky magnetic/electric resonances enables rapid
computational design of such metasurfaces.
