A refractive index sensor based on metal-insulator-metal coupling ring resonator with a stub

In this work, a refractive index sensor structure is proposed, which consists of the met-al-insulator-metal (MIM) waveguide coupling with ring resonator with a rectangular cavity. Its sensing characteristics are analyzed by the finite element analysis method. SPPs is an electromagnetic wave mode exc...
