A Novel Dual-Band Frequency Selective Surface Absorber

Fractal FSS: a novel dual-band frequency selective surface - Antennas and Propagation, IEEE Transactions on

The multiband properties of self-similar fractals can be advantageously exploited to design multiband frequency selective surfaces (FSS). A Sierpinski dipole FSS has been analyzed and measured and the results show an interesting dual-band behavior. Furthermore a near-field measurement technique is applied to characterize the FSS response to different angles of incidence. Finally, it will be sho...

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...

Study on Dual Wide Band Frequency Selective Surface for Different Incident Angles

This paper deals with single layer Frequency selective surface (FSS) which acts as a double band reject filter. The two stop bands are really broad with percentage bandwidth of 26.67% and 14.53%. The maximum and minimum band separation for this proposed design is around 45 dB and frequency ratio is more than 1.9.This results are almost same for different incident angles.. This design is investi...

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...
