Dual-band THz absorberPolarization-insensitive absorberWe present a design of a polarization-insensitive dual-band metamaterial absorber (MA) in the THz region by employing a three-layer structure consisting of a rectangular-shaped resonator on top of silicon and metallic film. Finite-difference time ...
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 materials and optimizing parameters, it can achieve the characteristics of both broadband and single peak absorption....
This paper presents the design, simulation and measurement of a dual-band terahertz metamaterial absorber with polarization-insensitivity and wide incident angle. The unit cell of the metamaterial consists of top resonator structures and low metallic ground plane, separated by an isolation material spacer...
We propose a dual-band metamaterial perfect absorber with a metal–insulator–metal structure (MIM) for use in infrared (IR) stealth technology. We designed the MIM structure to have surface plasmon polariton (SPP) and magnetic polariton (MP) resonance peaks at 1.54 μm and 6.2 μm,...

2022A dual-band/ultra-broadband switchable terahertz absorber based on vanadium dioxide (VO2) and graphene is proposed in this article. By controlling the properties of VO2 and graphene, the operation mode of the absorber can be switched between dual-band and ultra-wideband absorption. The simula...
