In the wake of intense research on metamaterials the two-dimensional analogue, known as
metasurfaces, has attracted progressively increasing attention in recent years due to the …

Metasurfaces as optically thin composite layers can be modeled as electric and magnetic
surface current sheets flowing in the layer volume in the metasurface plane. In the most …

Nonlinear optics is a well-established field of research that traditionally relies on the
interaction of light with macroscopic nonlinear media over distances significantly greater …

In this Perspective, we outline the recent progress, primary achievements, and further
directions in the development of high refractive index nanostructures and metasurfaces. In …

Planar optical chirality of a metasurface measures its differential response between left and
right circularly polarized (CP) lights and governs the asymmetric transmission of CP lights. In …

We present detailed analytical modeling and in-depth investigation of wide-angle reflect-
mode metagrating beam splitters. These recently introduced ultrathin devices are capable of …

The concentration and manipulation of light in the nanoscale range are fundamental to
nanophotonic research. Plasmonic nanoparticles can localize electromagnetic waves within …

Orbital angular momentum (OAM) is an intrinsic property that all electromagnetic waves can
carry. Interesting properties of OAM beams have enabled many novel applications. But …

Magnetoelectric dipole coupling effects in all-dielectric metasurfaces composed of particles
with bianisotropic electromagnetic response are investigated. This bianisotropic response is …

On the quest towards full control over wave propagation, the development of compact
devices that allow asymmetric response is a challenge. In this Letter, we introduce a new …
