The absorption of electromagnetic energy by a material is a phenomenon that underlies
many applications, including molecular sensing, photocurrent generation and …

The scattering of electromagnetic waves lies at the heart of most experimental techniques
over nearly the entire electromagnetic spectrum, ranging from radio waves to optics and x …

Recently, exceptional points, a degeneracy of open wave systems, have been observed in
photonics, acoustics, and electronics. They have mainly been realized as a degeneracy of …

Materials with anisotropic material parameters can be utilized to fabricate many fascinating
devices, such as hyperlenses, metasolids and one-way waveguides. In this study, we …

This paper proposes a vanadium dioxide metamaterial-based tunable, polarization-
independent coherent perfect absorber (CPA) in the terahertz frequency range. The …

We propose a temperature-tunable and dual-broadband switchable coherent perfect
absorber (CPA) composed of an annulus-disk-shaped InSb pattern and a complementary …

A suspended monolayer graphene has only about 2.3% absorption rate in visible and
infrared band, which limits its optoelectronic applications. To significantly increase …

Electromagnetic metamaterials are artificial subwavelength composites with periodic
structures, which can interact strongly with the incident light to achieve effective control of the …

Hybrid integration of nanoplasmonic devices with silicon photonic circuits holds promise for
a range of applications in on-chip sensing, field-enhanced and nonlinear spectroscopy, and …

A fiber optic-based all-optical amplifier is designed by using the coherent perfect absorption
phenomenon. For this purpose, we use a deposited chromium thin layer as an absorbent …
