• illuminated by such beams. We propose several configuration schemes where magnetic anapole modes of simple or hybrid nature can be detected in silicon nanospheres, nanodisks and nanopillars. Keywords: anapole excitation; dielectric nano-optics; multipolar expansion; T-matrix method; vector beams

• comparable toroidal and electric dipoles might result in nonradiating anapole excitation [10][11][12][13][14]. It has a number of interesting features and can be used to design near-field laser [15], to obtain high-efficiency harmonic generation [16], to achieve pure magnetic dipole scattering without

• , excitation of anapole states has also been examined under a projection scheme on Fano–Feshbach resonances [27]. For our purposes, we associate any zeros of the partial scattered power of spherical harmonics with the potential of nonradiating anapole excitation. Importantly, high-index dielectric
