The presented work involves designing a hybrid metasurfaces by incorporating merits of two different types of resonator system (metal and dielectric) and investigating novel optical features emerging from the metasurface. The metasurface design consists of a high-index resonator array on top of thick metal film with a spacer layer. Simulation studies on the metasurface shows that a strong coupling can be achieved between the anapole mode in the disk and a surface plasmon polariton (SPP) mode at the metaldielectric interface.
