Abstract

We present the tailored terahertz responses via the hybridization of magnetic and electric resonators under normal incidence of electromagnetic wave. These cross-I sandwiched structures enable us to couple out the negative magnetic resonance followed by the effective inductance-capacitance (LC) circuit model, along with the negative electric response contributed by the excitation of diluted Drude metal resonance, thus allowing the realization of negative refraction index with a value of -2.3 at 4 THz. Furthermore, the cross-I sandwiched structures possess the compelling sensing performance based on their remarkable sensitivity and high-quality resonant behavior, holding great potential for practical applications in chemical/biological detection.
