We study a class of temporal metamaterials characterized by time-varying dielectric
permittivity waveforms of duration much smaller than the characteristic wave-dynamical …

Nowadays the groundbreaking tools of contactless energy transfer reveals new
opportunities to supply portable devices with electrical energy by eliminating cables and …

While elastic metasurfaces offer a remarkable and very effective approach to the
subwavelength control of stress waves, their use in practical applications is severely …

The recovery of raw materials represents one of the greatest challenges for a circular
economy. Especially, the increased demand for lithium in the last years for its critical role in …

The accurate and efficient computation of the electromagnetic response of objects made
from artificial materials is crucial for designing photonic functionalities and interpreting …

We elaborate on an operator approach to effective medium theory for homogenization of the
periodic multilayered structures composed of nonmagnetic isotropic materials, which is …

Nonlocality is a fundamental concept in photonics. For instance, nonlocal wave-matter
interactions in spatially modulated metamaterials enable novel effects, such as giant …

Using the multiple-scale homogenization method, we derive generalized sheet-transition
conditions for electromagnetic fields at the surface of a metafilm. The scatterers that …

We propose using deep neural networks for the fast retrieval of effective properties of
metamaterials based on their angular-dependent reflection and transmission spectra from …
