） Abstract： We present here a wide-angle broadband waveplate based on a field transformation (FT) method
By adjusting the thickness of such waveplate, we obtain both half-wave and quarter-wave plates which achieve polarization conversions between TE (transverse electric) and TM (transverse magnetic), LCP (left-handed circular polarization) and RCP (right-handed circular polarization), linear and circular polarizations separately for both transmission and reflection cases
Such waveplates can be realized through sub-wavelength dielectric gratings based on effective media theory, whose performances have been verified through numerical and full-wave simulations with measurements carried out in microwave regime
In principle the proposed prototype is applicable from radio to optical frequencies
