Abstract
An anapole, a non-radiating charge-current configuration, has been recently observed in a variety of artificial materials and nanostructures. A dynamic anapole originates from the destructive interference of the waves generated by electric and toroidal dipole moments induced in the nanoparticles by incoming radiation. Here we present a direct experimental observation of a polarization-independent anapole detected in a trimer-based all-dielectric metasurface. An analysis is performed to study the tolerance of anapole to the effects of oblique wave incidence and material losses existing in real metasurfaces. The manifestation of anapole is confirmed by checking the resonant states in the reflection characteristics, near-field patterns, and conditions of multipole moments of the trimer obtained from the full-wave numerical simulations. The presented metasurface bears a polarization-insensitive anapole state which can be utilized in various applications from sensors to lasers.
