Abstract :
By embedding polarization-independent four-rod resonators into polarization-dependent double-split ring resonator superlattice metamaterial, a polarization-dependent Fano resonance is experimentally demonstrated in THz regime. A finite-difference time domain simulation shows that a destructive coherent coupling between radiative bright dipole mode in double split ring resonator and non-radiative dark anti-dipole mode in four-rod resonators is responsible for Fano resonance.
