Their analytical solutions were achieved for both TE and TM polarizations utilizing the generalized Snell＇s law. The calculated results show that the GH shifts are evidently affected by phase gradients and incident angles, which means that a certain range of GH shifts can be realized as long as an incident angle, phase gradient, and frequency are properly chosen. This offers an effective method for the control of GH shifts.展开更多
