A topological photonic crystal with ultra wide dual bandwidth
We demonstrated a sandwich topological photonic crystal (PC) structure with C6 honeycomb medium column, the background material of PC is E7 liquid crystal. The results show that the working bandwidth of the laminated PC with liquid crystal as the background material can be changed by voltage, i.e.,...
