Design of a Reconfigurable Linear-to-Linear Polarization Conversion Metasurface

A reconfigurable polarization conversion meta-surface (PCM) is proposed, which can reflect the linear polarization (LP) wave into the orthogonal LP wave or LP wave with same polarization. In conversion mode, the proposed Re-PCM can operate over 4.5GHz∼5.5GHz maintaining the
$\Gamma \text{xx}$
less than - 15dB. In reflection mode, the proposed Re-PCM acts as a metal reflector.
