From: Realization of deep subwavelength resolution with singular media
The results at 1.5 GHz are enclosed in the top panel (a–c) while the results at 10 GHz are enclosed in the bottom panel (d–f): the simulated field distributions (a, d) for the case without meta-lens and (b, e) for the case with meta-lens and (c, f) the image intensity normalized by the input intensity.
In the experiment, the distance between the receiver and the center is 0.6 m.
