Co-excitation of magnetic anapole and quasi-BICs in an all-dielectric Si dimer metasurface.

Co-excitations of diverse non-radiative scattering states in a single metasurface are promising for multifunctional nanophotonic devices. Anapole and bound state in the continuum (BIC) are two typical manifestations of nonradiation; however, it is ch…
