Abstract
Even though the study of non-radiating objects has been part of fundamental physics for a long time, the dynamic anapole corresponding to the time-varying oscillating charge-current distributions in the optical frequencies was only experimentally demonstrated in 2015. In this talk, I will report the results of excitation of anapole mode in isotropic nanosphere. Since plane wave illumination is not suitable for anapole mode excitation in a nanosphere, we exploited the polarization symmetry of cylindrical vector beam to excite anapole mode in isotropic nanosphere.
