Fano Resonances in All-Dielectric Oligomers
We demonstrate that light scattering by all-dielectric oligomers exhibits well-pronounced Fano resonances with strong suppression of the scattering cross section. Our analysis reveals that this type of the Fano resonance originates from the optically induced magnetic dipole modes of individual high-dielectric nanoparticles.

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces
Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

Neural networks can accelerate modeling and inverse design of electromagnetic devices by several orders of magnitude, but usually require large amounts of data to train. This work demonstrates that integrating knowledge about quasinormal modes into the network architecture reduces the required amount of training data significantly, while simultaneously

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films
We measure the optical response of poly[3,4‐ethylenedioxythiophene] thin films through the combination of polarized photon spectroscopies (variable‐angle ellipsometry, UV–mid‐IR reflectance and transmittance) and wide‐angle X‐ray scattering, revealing anisotropic optical response and conductivity and enabling structural modelling of chain and π‐system ...

Double Fano resonances in a composite metamaterial possessing tripod plasmonic resonances
Double Fano resonances are observed in a planar composite metamaterial possessing tripod plasmonic resonances, where a common subradiant driven oscillator is coupled with two superradiant oscillators.
