Fig. 4. Magnetic field enhancement ratio of the metamaterials.

Fig. 4.

(a) Magnetic field enhancement ratio as a function of distance from the center of the metamaterial array (along the white dashed line in (b)) with simulation and calculation results in blue and red. Regions A, B, and C correspond to the regions within the metamaterial array, the region extending from the surface of the metamaterial to the peak enhancement ratio, and the ‘sample region’ beyond the peak enhancement, respectively. The inset illustrates an extended plot of Region C (‘sample region’). (b) The magnetic field strength along the axial direction distributed at the cross section depicted as the blue rectangle in the inset. (c) The theoretical magnetic field enhancement ratio of metamaterials with unit cells with different diameters.
