Photoswitchable Anapole Metasurfaces
Advanced Optical Materials, 2021Abstract Nonradiating charge‐current configurations have attracted attention in photonics for the efficient localization of the electromagnetic field. Anapole mode is a unique nonradiating state of light induced by the interference of electric and toroidal dipole that possesses rich physics with potential applications in micro ...

This chapter reports design and analysis methods for planar antennas based on modulated metasurfaces (MTSs). These antennas transform a surface wave (SW) into a leaky wave by means of the interaction with a MTS having a spatially modulated equivalent impedance.

Perovskite Metamaterials and Metasurfaces
2021Nanophotonics has emerged in recent years as the branch of science capable of connecting conventional optics with nanoscale phenomena. The key feature enabling this convergence is the ability of nanosized photonic objects to confine light within volumes comparable to or smaller than their physical sizes, far beyond the wavelength of the optical ...

Metasurface and metamaterial by design
2014 International Radar Conference, 2014The synthesis of high-performance and complex electromagnetic devices is carried out through an innovative approach. The features of metasurfaces and metamaterials are exploited to design innovative field manipulation devices. More in detail, a set of instances of the System-by-Design paradigm are applied to the synthesis of metasurface and ...

Modeling refractive metasurfaces in series as a single metasurface
SPIE Proceedings, 2016Metasurfaces are boundaries between two media that are engineered to induce an abrupt phase shift in propagating light over a distance comparable to the wavelength of the light. Metasurface applications exploit this rapid phase shift to allow for precise control of wavefronts.

Metasurfaces for Molecular Emitter
2022 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR), 2022We demonstrate extraordinarily spectrally selective narrowband mid-infrared radiation absorbance and thermal emittance with the strong surface enhancement of molecular infrared absorption (SEIRA) using mid-midinfrared metasurfaces. This was achieved by harnessing mode coupling between a plasmonic metal-insulator-metal (MIM) metasurface and molecular ...
