Fano resonance on substrate integrated waveguide loaded plasmonic metamaterial

In this paper, a Fano resonance structure based on substrate integrated waveguide (SIW) is proposed. The structure consists of a slotted substrate integrated waveguide coupled to an artificial localized surface plasmons resonator. The Fano resonance was excited by coupling the electromagnetic energy in the SIW to the top-loaded artificial localized surface plasmons resonator. The Fano resonance can be effectively tuned by modifying the geometrical parameters of subwavelength structures. Numerical simulation shows that our work has greatly strengthened Fano resonance intensity.
