We studied new left-handed material composed of hexagonal split resonant rings SRRs based on trigonal resonators and metal wires through simulation and experiment. Simulated negative permeability material based on periodic structures of trigonal SRRs, in contrast to simulation result based on closed split resonant rings CSRRs, we found that the trigonal SRRs can generate negative permeability, and multilayer SRR simulation shows the coupling can enhance the resonant frequency and broaden resonant frequency band. We designed a new kind of left-handed material combined with hexagonal resonator based on trigonal resonators and copper wires. Simulation shows that the structures have good left-handed property. We have fabricated experimental samples which show negative refraction when the frequency lies in 93—108 GHz rangc. This has important significance on design and study of new types of periodic structures of left-handed materials.
