An individual's health is one of the essential aspects of life, but due to the limited technology
at health care centers, many people face various restrictions during their treatment. These …

Chiral nanomaterials with intrinsic chirality or spatial asymmetry at the nanoscale are
currently in the limelight of both fundamental research and diverse important technological …

Graphene sensors leverage graphene's exceptional electrochemical properties to provide
high sensitivity and efficiency. This study presents a meta surface-based sensor specifically …

One of the fastest-expanding study areas in optics over the past decade has been
metasurfaces (MSs). These subwavelength meta-atom-based ultrathin arrays have been …

Optical metasurfaces are thin‐layer subwavelength‐patterned structures that interact
strongly with light. Metasurfaces have become the subject of several rapidly growing areas …

Metamaterials are artificial media structured on a size scale smaller than wavelength of
external stimuli, and they can exhibit a strong localization and enhancement of fields, which …

As the counterpart of electromagnetic and acoustic metamaterials, elastic metamaterials are
artificial periodic elastic composite materials offering the possibility to manipulate elastic …

The terahertz (THz) region lies between the microwave and infrared regions of the
electromagnetic (EM) spectrum such that it is strongly attenuated by water and very sensitive …

In the past two decades, the development and steady improvement of terahertz technology
has motivated a wide range of scientific studies designed to discover and develop terahertz …

In this paper, we review the principal theoretical models through which the dielectric function
of metals can be described. Starting from the Drude assumptions for intraband transitions …
