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 …

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 …

As the demand for cognitive understanding of the THz band continues to grow, there is
significant potential for practical applications in designing optical devices operating in this …

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 …

In recent decades, the world's environmental troubles have become increasingly serious.
Seeking new and environmentally friendly energy sources to replace chemical fuels is the …

In recent years, vertical graphene nanowalls (VGNWs) have gained significant attention due
to their exceptional properties, including their high specific surface area, excellent electrical …

In this paper, a terahertz absorber based on monolayer graphene is proposed. Compared
with other absorber structures, the structure is very simple, which is conducive to the …

Abstract Development of highly-efficient heterojunction piezo-photocatalysts offers a great
