Abstract

We demonstrate the active control of resonant frequency in terahertz (THz) metamaterial comprised of split ring resonator arrays (SRRs). It is found that the introduction of different substrates can greatly modify the sensing capabilities of the SRRs structure, i.e., the SRRs designed on PET (polyethylene terephthalate) is more sensitive to THz wave accompanied with higher resonance frequency as well as wider non-resonant region. Furthermore, our simulated findings indicate that THz response sensitivity can be distinctly tuned by changing the gap of SRRs on PET. The mechanism of inductance-capacitance (LC) resonance and dipole resonance is exploited to explain the varied THz transmission responses. Our work infers that the SRRs structure based on PET with low dielectric constant is a significantly better option for biological and chemical sensing applications.
