Focal Shift of Nano-Optical Lens Affected by Periodic Resonance With Substrate
A method of focal-shift resonance with substrate based on two commonly used structures of nano-optical lens is presented with numerical simulations. This resonance exhibits periodicity with the variation of substrate refractive index. Both types of lenses are based on gradual changed nanoslits and a...
