Optical metamaterials have presented an innovative method of manipulating light.
Hyperbolic metamaterials have an extremely high anisotropy with a hyperbolic dispersion …

The scientific effort to control the interaction between light and matter has grown
exponentially in the last 2 decades. This growth has been aided by the development of …

Chirality has a key role in the synthesis of biomolecules and the development of life.
Although the effects of many chiral molecules or materials on biological processes have …

Biosensors have been designed and developed for detecting biomarkers, biomolecules,
proteins, enzymes, organisms, and various types of bacterial and viral diseases since the …

Due to the unique nature of localized surface plasmon resonance (LSPR), LSPR has
attracted extensive attention in the field of biochemical sensing. However, compared with …

Surface plasmonic sensors have been widely used in biology, chemistry, and environment
monitoring. These sensors exhibit extraordinary sensitivity based on surface plasmon …

An inverted pyramidal metasurface was designed, fabricated, and studied at the nanoscale
level for the development of a label-free pathogen detection on a chip platform that merges …

Metasurfaces are planar or 2D forms of metamaterials made up of arrays of antennas with a
subwavelength thickness. They have been rapidly developed in the recent years due to their …

Without using intrinsic chiral metamaterials with complex structures, here we use achiral
metasurfaces to realize giant extrinsic chirality empowered by quasi-bound states in the …

In this paper, we theoretically propose a highly sensitive terahertz sensor based on a
graphene metamaterial absorber in the THz region. The numerical analysis of the proposed …
