چکیده
Lensshaped particles with different sizes for various refractive indices have been investigated under plane wave illumination by using 2DMMP simulation. Distribution of the power in the vicinity of opposite boundary of the particle has resulted in a tightly focused photonic nanojet in specific conditions. The results show that the beam waists are smaller than the diffraction limit, and they propagate over several optical wavelengths without significant diffraction while the beam reaches a high intensity. In this paper, it is argued the manipulation of various dielectric lens shapes with respect to a highly confined power distribution in the producing nanojet has been parameterized according to the beam waist and divergence with regards to particular refractive index (glass, plastic and patinal), and appropriate structure shapes. Optimized dimensions of the nanojets for different physical properties are calculated.
