Split ring resonators (SRRs) can be used as a negative permeability medium near its magnetic resonance frequency. In this paper, a new type of THz-band magnetic resonance structure is proposed by introducing metal wires into traditional SRRs, and the effect of metal wires on the transmission characteristics of SRRs is numerically investigated. The results show that the resonant frequency of SRRs significantly decreases with the number of metal wires increasing. The parameters of metal wires, such as length Lx, width Wx and distance Gx also have influence on the resonant frequency of SRRs. Meanwhile, the results verify that the introduction of metal wires play an important role in reducing the size of the device, and cannot be affected by the presence of dielectric substrate. The new magnetic resonance structure proposed in this paper provides a reference for the design and practical applications of metamaterials in the future.
