An ultra-narrowband terahertz (THz) perfect absorber with metal-insulator-metal (PA-MIM)
microstructures is presented. MIM microstructures is composed of Al disk on SiO 2/Al/Si …

A multiple broadband terahertz (THz) perfect absorber which can be dynamically adjustable
is designed, consisted of the vanadium dioxide (VO 2) layer, a metal ground plane, and a …

Terahertz (THz) perfect absorber, as a useful functional device, has attracted considerable
attention. Traditional metamaterial perfect absorbers are usually in response to single …

Broadband absorber in the terahertz region (0.1–10 THz) has attracted considerable
attentions due to its important applications in detecting, imaging, and electromagnetic …

In this paper, a tunable terahertz metamaterial absorber with two bands is proposed. It is
composed of Au reflector, dielectric layer and periodic array of Au. By adjusting different …

The temperature independent ultra-broadband THz metamaterial absorbers based on
square resonator are designed. The absorber is composed of surface metal resonance ring …

Terahertz (THz) absorbers have attracted considerable attention due to their potential
applications. However, the limited bandwidth of THz absorbers limits their further …

Terahertz (THz) absorbers with high absorptivity across a wide frequency band have
attracted considerable interest. In this paper, we present the design of an ultra-broadband …

In this work, we numerically demonstrated a single narrow band THz absorber based on
cylindrically shaped periodical p-type doped silicon with excellent attributes, including …

A tunable broadband metamaterial absorber is proposed based on the vanadium dioxide
and Fabry-Perot cavity in the terahertz region. To broaden the absorption bandwidth, the …
