Nonradiating sources of energy have traditionally been studied in quantum mechanics and
astrophysics but have received very little attention in the photonics community. This situation …

Metasurfaces have attracted a lot of attention in recent years due to the alternative methods
they provide for the efficient wavefront control and engineering of resonant transmission. We …

Metasurfaces without a mirror symmetry may exhibit chiral electromagnetic response that
differs substantially from any type of polarization transformation. A typical design of chiral …

This paper reports the results of a field experiment investigating how attributes of carbon
footprint information affect consumer choice in a large dining facility. Our hypotheses and …

Light absorption plays a vital role in governing the performance of optoelectronic devices,
such as solar cells and photodetectors. However, it is quite challenging to realize perfect …

In this Letter, we propose a symmetric metasurface composed of single-sized amorphous-
silicon (a-Si) cuboids tetramer clusters that support two resonances with opposite symmetry …

The toroidal dipole is a fundamental electromagnetic excitation independent from the well-
known electric and magnetic dipoles, which enables strong resonances in nanostructure …

Oligomer metasurfaces have attracted a lot of attention in recent years because of their
ability to drive strong resonance effects. In this work, by perturbing the symmetry of the …

Asymmetric metasurfaces supporting quasi-bound states in the continuum (BICs) with high
Q-factors and strong light–matter interaction properties are attractive platforms for label-free …

Ultra-high quality (Q) factor resonances derived from the bound states in the continuum
(BICs) have drawn much attention in optics and photonics. Especially in meta-surfaces, they …
