摘要：

In this paper, broadband dual tilted Bessel beams with the aid of a polarization conversion meta-surface is generated. The transmission meta-surface consists of 32*32 subwavelength unit cells, which can effectively convert incident linear polarized wave to zero order Bessel beam with different direction based on time reversal. The designed three-layer unit cell combining mirrored and size changed approach can meet the need of full 360 degrees phase coverage from 10GHz to 18GHz with high transmission magnitude (>0.9).The developed dual Bessel beams propagate along the theta = 30 degrees, phi = 45 degrees and theta = -30, phi = 180 degrees. And their simulated magnitude distributions in near field are provided.
