摘要:
A metallic-microstructure composite, which is comprised of deformed-split-ring resonators (DSRRs) and wires, is shown to preserve the transmission characteristics of a left-handed metamaterial, implying the simultaneously negative values of effective permeability and permittivity, as well as a wider bandwidth of resonance. Furthermore, the DSRR is so designed that it minimizes the size of the unit cell for fabrication, which is favorable for the implementation of left-handed metamaterial in near infrared region.
