Abstract :
An automatic design and fabrication method for a broadband circular-polarized gradient index metamaterial (GIM) lens is proposed. There two key points: Firstly, the GIM lens consists of isotropic dielectric plate with deep-subwavelength through-holes, which have very little influence on the polarization states of incident waves; Secondly, the analytical formulas for the distribution rules of the through-holes on the plate is derived. This method is numerically and experimentally validated.
