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 …

During the past few years, metasurfaces have been used to demonstrate optical elements
and systems with capabilities that surpass those of conventional diffractive optics. Here, we …

Thermal radiation is one of the three ways of heat transfer, among which the mid-infrared
thermal radiation has attracted much attention. At present, static control of thermal emissivity …

This paper introduces a novel metamaterial absorber based on surface plasmon resonance
(SPR). The absorber is capable of triple-mode perfect absorption, polarization …

Here, a simple four-band terahertz tunable narrowband absorber is proposed, which can
achieve multimodal perfect absorption within 1–9 THz. We analyzed the physical …

Solar energy is currently a very popular energy source because it is both clean and
renewable. As a result, one of the main areas of research now is the investigation of solar …

In this paper, we propose a terahertz (THz) micronano device that can actively switch
between bimodal absorption and plasmon-induced transparency (PIT). The device mainly …

When surface plasmon resonance (SPR) occurs, the incident light is absorbed by the
surface of the SPR structure, thus minimizing the intensity of the reflected light. Therefore …

This paper presents a novel graphene-based proportional structure for a tunable wideband
absorber in the terahertz (THz) frequency range. In order to achieve the ideal design …

In this paper, a six-band rotationally symmetric tunable absorption film based on AlCuFe
quasicrystals is proposed. The absorption film has a symmetrically excited electric field …
