Abstract

We reveal the peculiarities of the trapped mode manifestation in metasurfaces composed of an array of MoS2 disk-shaped resonators. The corresponding resonance arises as a result of the excitation of the electric octupole moment existing in each meta-atom of the metasurface and multipole coupling effects in the array. In particular, we show that the effect appears due to a lattice-induced coupling between the electric octupole and electric dipole moments in the metasurface. The coupling effect between the resonant quasi-trapped octupole mode and the suppressed electric dipole results in the appearance of the narrow-band transparency conditions in the metasurface spectra with a simultaneous storing of electromagnetic energy inside the resonators. The discussed approach is quite general and can be implemented in metasurfaces supporting Mie-type modes in meta-atoms made of different materials.
