A terahertz (THz) metamaterial absorber based on a split ring resonator (SRR) structure was used to realize the highly accurate detection of trace pesticides, including indole-3-acetic acid (IAA) and tricyclazol
A straightforward structure based on TiNi alloy films is adopted, but it can achieve the design objectives of a dynamically tunable and polarization-insensitive dual-band terahertz metamaterial absorber. The structure schematic of our proposed THz MMAs, as shown in Fig. 1(a), whose unit cell cons...
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,...

Here, a high-sensitive dual-band sensor based on the complementary terahertz metamaterial composed of microsize circular ring gap array is proposed to detect the thickness and refractive index of thin film. The structure of this sensor is polarization insensitive dual-band operating mode and can be...

The design, simulation and analysis of a dual-band metamaterial absorber(MMA) working at the microwave frequencies are presented. The single unit cell consists of two nested closed hexagon ring resonators and a metallic background plane, separated by a dielectric layer with only 0.7-mmthickness. ...
