Dimensions and magnetic field of the modified asymmetric metamaterial structure in different views. (a) Periodic unit of the asymmetric metamaterial. Loop1 and loop2 has the same area of \(\:{S}_{1}\), loop1’ and loop2’ has the same area of \(\:{S}_{2}\); (b) The structure in view Z. (c) Magnetic field on x direction in the periodic unit; (d) Magnetic field on y direction in the periodic unit.
