Abstract: (1648 Views)
In this paper, photonic nanojets are achieved using circular and elliptical dielectric cylinders in air background. Therefore, for obtaining high intensity and large focal length photonic nanojets, using high-resolution finite difference time domain method, the optical properties of obtained nanojets are studied for all possible geometrical parameters. Numerical results show that the field intensity of circular photonic nanojet is higher than the elliptical one, while the focal length of elliptical photonic nanojet is greater than that of circular one. These results can be helpful in designing advanced photonic components such as ultra-sensitive particle sensors.
