An ultra-thin metasurface is proposed to realize wideband polarization-independent anomalous reflection. The gradient metasurface is done by 6 discrete orientation of the local sub-wavelength resonator, which provides a phase gradient. The simulation and measured results show that 9 GHz bandwidth of the anomalous reflection is achieved.
A gradient metasurface is proposed to obtain both surface wave coupling and anomalous reflection. The unit cell of the gradient metasurface is composed by six electric field coupled resonators in different rotation angle, which provides a phase gradient. The simulation and measured results show that this gradient metasurface can work at 7.8 GHz as a surface wave coupler and at 10.288 GHz providing...
