Abstract: We introduce a general concept and consider a characteristic approach to obtain the narrow-band suppression of total electromagnetic scattering independent of the irradiation conditions for the compound dielectric structures supporting unique anapole states. To emphasize this independence from the irradiation conditions, we call the selective superinvisibility effect. We show that the realization of this concept allows us to reach simultaneously several goals significantly suppress the scattering (at a certain wavelength); provide the scattering suppression for any polarization and direction of incidence waves; accumulate electromagnetic energy in the near-field zone and inside of the scatterer. The combination of these physical properties in a compound structure makes it possible to consider them as building blocks for two-dimensional or three-dimensional metamaterials with the selective transparent property practically independent of the irradiation conditions. Our study includes theoretical modeling based on a multipole approach and a corresponding experimental verification.
