The applicability of the method is demonstrated on specific examples of single- and bi-layers of periodically modulated high-refractive-index spherical particles arranged on a square lattice. The results provide compelling evidence for strong and tunable inelastic scattering effects under the triple resonance condition, fulfilled for optical transitions between neighboring high-&lt;/span&gt;&lt;em&gt;Q&lt;/em&gt;&lt;span&gt;&amp;nbsp;lattice modes of the appropriate symmetry, which originate from multipolar Mie resonances. A consistent interpretation of the underlying mechanisms is provided and potential applications in the design of nonreciprocal devices are&amp;nbsp;discussed.&lt;/span&gt;</style></abstract><issue><style face="normal" font="default" size="100%">12</style></issue></record></records></xml>
