Tunable polarization-controlled perfect switching of transverse scattering

We demonstrate the polarization-controlled perfect switching effect in near-infrared frequency ranges using silicon particles embedded in a liquid crystal cell. The effect has electric field tunable properties in a wide frequency band. The phenomenon originates from the interaction between electric multipole modes and magnetic multipole modes, which can also be generalized to the visible and other frequency ranges. It is expected that such an electric field tunable switching device can play important role in the optical information process.
