Multipole Resonances in Dielectric Metasurfaces: Rethinking Light Control
Key Takeaways
- Dielectric metasurfaces have moved to the forefront of nanophotonics as flat, low-loss alternatives to conventional bulk optical elements.
- They control amplitude, phase and polarization of light rather than relying on thickness and curvature.
- Dielectric platforms reduce the absorption losses associated with plasmonic metal-based designs.
- Engineered multipole resonances — electric and magnetic dipoles, higher-order terms and their interference — determine how a metasurface transmits, reflects or absorbs light.
