Hybrid nanostructures exhibit extraordinary optical properties achieved by the combination of metal and dielectric components in a single nanostructure. Here we numerically study optical properties of metal-dielectric (hybrid) sphere-gap-cone nanostructure. Numerical simulation related to scattering cross section demonstrates that this nanoantenna possesses strong magnetic and electric response in the visible range. In addition, looking into resonant wavelengths indicate this nanostructure is
