Abstract

This study focuses on the photonic nanojets generated by micro-cylinders with nanostructured surfaces using FDTD method. When micro-cylinders are embedded in different medium such as air or water, the dimension and maximum intensity of the generated photonic nanojets will change, as well as the distance between the micro-cylinders and the photonic nanojets. More importantly, photonic nanojet may disappear when a rough surface micro-cylinder is used due to the strong random scattering and interference effect. In practice, these numerical study results can provide guidance when using photonic nanojets for imaging nanoscale objects.
