All-dielectric ellipsoid for hybrid anapole observation

We investigate all-dielectric flattened ellipsoid particle on dielectric substrate for demonstration of hybrid anapole mode. We find that such particle could support first and second order electric and magnetic anapole modes that manifesting fully eliminated scattering of the structure. We demonstrate scattering properties of high index all-dielectric ellipsoid particle and provide multipole decomposition on the scattering minimum.
