In this study, we investigate metallic nanophotonic lenses that consist of multiple nano-ring apertures. Emphasis was placed on a nanophotonic lens of simple two nano-ring apertures modeled on a BK7 substrate with capping and adhesion layers. Electromagnetic fields were numerically calculated in response to metal, substrate, and ambient changes when the distance of two nano-ring apertures varies at an aperture depth and width fixed at 50 and 350 nm. The results indicate that control over fairly broad ranges of focal lengths and intensities can be achieved, which is expected to be useful to implement an optical element for various nanoscale imaging applications.
