Experimental verification of multi-band metamaterial absorber with double structured layers

A dual band terahertz metamaterial absorber

We present the design, fabrication and characterization of a dual band metamaterial absorber which experimentally shows two distinct absorption peaks of 0.85 at 1.4 THz and 0.94 at 3.0 THz. The dual band absorber consists of a dual band electric-field-coupled (ELC) resonator and a metallic ground plane, separated by an 8μm dielectric spacer. Fine tuning of the two absorption resonances is achie...

Design, Fabrication and Measurement of Two-Layered Quadruple-Band Microwave Metamaterial Absorber

The design, simulation, fabrication, and measurement of two structures of metamaterial absorbers (MA) is investigated at microwave frequency in this paper. By stacking of one layer structure on the top of each other, a two-layered structure is generated. The unit cell at each layer consisting of two sets of various circular and square patches are designed so that the structure exhibit quad band...

Miniaturization for ultrathin metamaterial perfect absorber in the VHF band

An efficient resolution for ultrathin metamaterial perfect absorber (MPA) is proposed and demonstrated in the VHF radio band (30-300 MHz). By adjusting the lumped capacitors and the through vertical interconnects, the absorber is miniaturized to be only λ/816 and λ/84 for its thickness and periodicity with respect to the operating wavelength (at 102 MHz), respectively. The detailed simulation a...

Dual band complementary metamaterial absorber in near infrared region

A terahertz polarization insensitive dual band metamaterial absorber.

Metamaterial absorbers have attracted considerable attention for applications in the terahertz range. In this Letter, we report the design, fabrication, and characterization of a terahertz dual band metamaterial absorber that shows two distinct absorption peaks with high absorption. By manipulating the periodic patterned structures as well as the dielectric layer thickness of the metal-dielectr...
