摘要：

Here, we show theoretically and numerically that gradient metasurfaces can be used for converting evanescent waves to propagating ones. This conversion is useful for far field subwavelength imaging, where information about subwavelength features of a target object is contained within the evanescent waves and can not be detected at far field.
