Multipole decomposition of the localized current plays an essential role in a wide range of disciplines in modern physics, starting from the design of nanoantennas in photonics to the description of exotic states of matter. In the latter context, a third group of multipoles, toroidal multipoles, complementing the electric and magnetic ones, have been thoroughly investigated due to their lead to the formation of so-called anapole states, non-radiating sources. And further investigation shed light on the existence of higher-order toroidal dipoles, or equivalently, mean-square radii. Here we develop the classical anapole state obtained by destructive interference of electric and toroidal dipoles into the toroidal anapole which arises by destructive interference of electric toroidal dipole with first mean-square radius of electric toroidal dipole, presenting an analytical condition of such a state. #CSOC1120.
