Reconfigurable optical metasurfaces are rapidly emerging as a major frontier in photonics
research, development and commercialization. They promise compact, lightweight and …

Time-varying media have recently emerged as a new paradigm for wave manipulation, due
to the synergy between the discovery of highly nonlinear materials, such as epsilon-near …

Metasurfaces, the ultrathin, 2D version of metamaterials, have recently attracted a surge of
attention for their capability to manipulate electromagnetic waves. Recent advances in …

This broad review summarizes recent advances and “hot” research topics in nanophononics
and elastic, acoustic, and mechanical metamaterials based on results presented by the …

Over the past decade, static metasurfaces have proved to be low-profile and efficient
apparatuses for transformation of electromagnetic waves. However, such metasurfaces are …

We present a general framework for the homogenization theory of space-time
metamaterials. By mapping to a frame comoving with the space-time modulation, we derive …

Temporal interfaces introduced by abrupt switching of the constitutive parameters of
unbounded media enable unusual wave phenomena. So far, their explorations have been …

Wave absorption in time-invariant, passive thin films is fundamentally limited by a trade-off
between bandwidth and overall thickness. In this work, we investigate the use of temporal …

In this opinion article, we briefly summarize some of the background materials and recent
developments in the field of temporal and spatiotemporal media and provide our opinion on …

An accurate and simple analytical model for the computation of the reflection amplitude and
phase of Reconfigurable Intelligent Surfaces is presented. The model is based on a …
