Subwavelength focusing of azimuthally polarized beams with vortical phase in dielectrics by using an ultra-thin lens
Kun Huang, Huapeng Ye, Hong Liu +3
We demonstrate that a planar and ultrathin binary lens can focus an azimuthally polarized beam with vortical phase (APV) to a subwavelength spot of transverse polarization. The res…

Manipulating dc currents with bilayer bulk natural materials
Tiancheng Han, Huapeng Ye, Yu Luo +4
The principle of transformation optics has been applied to various wave phenomena (e.g., optics, electromagnetics, acoustics and thermodynamics). Recently, metamaterial devices man…
