The simulated transmission spectra (a) and the calculated group delay (b) of the proposed metamaterials composed of a strip and a ring without the graphene layer. The geometric parameters are consistent with Fig. 1. (c)–(e) The electric field Ez distributions corresponding to the three feature points represented by f 1, f 2, and f 3 in (a).
