Terahertz Metamaterials with Simultaneously Negative Electric and Magnetic Resonance Responses based on Bimaterial Pop Up Structures

In this paper, we present a metamaterial with simultaneously negative electric and magnetic resonance responses in the terahertz (THz) frequency range. The structure is composed of in-plane split resonator rings (SRRs) for desired electric response and out-of-plane SRRs realized by bimaterial pop up structures for magnetic response. Experimental results conducted using THz Time Domain Spectroscopy (THz-TDS) show that the presented metamaterial has both electric and magnetic resonance peaks at 0.5 THz. The performance of the metamaterial can be further improved by optimization of the structure´s geometry and the operating frequency of the metamaterial can be tuned by scaling dimensions.
