Realization of deep subwavelength resolution with singular media. Scientific Reports, 4, 5212-. | Series/Report no.: | Scientific reports | Abstract: | The record of imaging resolution has kept being refreshed in the past decades and the best resolution of hyperlenses and superlenses so far is about one out of tens in terms of wavelength. In this paper, by adopting a hybrid concept of transformation optics and singular media, we report a broadband meta-lens design methodology with ultra-high resolution. The meta-lens is made of subwavelength metal/air layers, which exhibit singular medium property over a broad band. As a proof of concept, the subwavelength imaging ability is demonstrated over a broad frequency band from 1.5–10 GHz with the resolution varying from 1/117 to 1/17 wavelength experimentally. | URI: | https://hdl.handle.net/10356/102906 http://hdl.handle.net/10220/20010 |
