The magnetic field pattern in the plane near and below the SRR metalens at 3.55 GHz.
(a) Structure of the SRR metalens with eight small loop sources. The metalens and small loops are located in the planes of z = 0 and z = 0.5 mm. When Cell A or Cell B is turned on, the magnetic field patterns in the plane of z = −2 mm at 3.55 GHz are shown in (b) and (c), respectively. The magnetic field intensities corresponding to (b) and (c) at the line of x = 12 mm are shown in (d). The line of x = 12 mm is through the centres of Cell A and B.
