Abstract :
The extracting method of the effective permittivity and permeability of split-ring resonator (SRRs for short) of metamaterials is described based on the extraordinary electromagnetic properties of metamaterials. Simulations are made to three types of symmetric SRRs by CST software. Comparison and analysis indicate that SRRs with short metal rod can regulate the resonating frequency of the SRRs. It is also verified that the transmission zero points of the new type of SRRs-based filter can be controlled by changing the distance between the short metal rod and the side of SRRs with mouth.
