摘要
We demonstrate a simple terahertz metamaterial design to increase the fundamental resonance bandwidth by embedding a metal strip inside a nested structure composed of two rings. The bandwidth of the fundamental resonance is 443 GHz which is 4.2 times larger than the bandwidth of the nested structure. And the increase in fundamental resonance broadening is attributed to the reduced effective inductance.This proposed structure provides a meaningful way toward expanding the fundamental mode operating range from narrowband to broadband with a tunable behavior.
