Image shows M.H., CEO of JCMwave, at Malaga, META2025 conference. https://metaconferences.org/META25/index.php/META/index In this contribution, we present a rigorous method for calculating resonance modes from scattering solutions of nanophotonic systems. We demonstrate its application in computing resonant states in periodic nanostructures such as metasurfaces, nanostructured waveguides, and other photonic systems. https://doi.org/10.1002/lpor.202400584 https://doi.org/10.1002/lpor.202500811

A Framework to Compute Resonances Arising from Multiple Scattering Photonic resonances frequently arise from the interaction among multiple scatterers. It is shown how prior knowledge of such constituents can be used to compute resonances in nanophotonic systems eff...
