Optical metasurfaces consist of 2D arrangements of scatterers, and they control the
amplitude, phase, and polarization of an incidence field on demand. Optical metasurfaces …

Metasurfaces with bound states in the continuum (BICs) have proven to be a powerful
platform for drastically enhancing light–matter interactions, improving biosensing, and …

Despite significant advances in the field of phononic crystals, the development of acoustic
metafluids that replicate the behaviour of liquids in three dimensions remains elusive. For …

Diffraction efficiency and polarization sensitivity are key performance indicators of diffraction
grating, which affect the accuracy of spectral information of imaging spectrometers. In this …

Open cavities are often an essential component in the design of ultra-thin subwavelength
metasurfaces and a typical requirement is that cavities have precise, often low frequency …

We present the realization of a vectorial perturbation method based on the Born series
applied to strong electromagnetic scattering problems. We present the general theoretical …

Polarization-insensitive beam splitters play significant roles in the manipulation of optical
beams and signal processing. However, existing fabrication methods for glass beam …

The rigorous solution to the grating diffraction problem is a cornerstone step in many
scientific fields and industrial applications ranging from the study of the fundamental …

Off-plane reflection gratings were previously predicted to have different efficiencies when the
incident light is polarized in the transverse-magnetic (TM) versus transverse-electric (TE) …

This paper describes a compact circularly polarized antenna designed for the 2.4 GHz band
