Microwave-absorbing materials have attracted enormous attention for electromagnetic (EM) pollution. Herein, hollow beaded Fe3C/N-doped carbon fibers (Fe3C/NCFs) were synthesized through convenient electrospinning and subsequent thermal treatment. The special morphology of the samples is conducive to achieve lightweight broadband microwave absorption properties. treatment temperatures exhibit a significant impact on conductivity EM broadest effective bandwidth (EAB) 5.28 GHz at 2.16 mm when...
We present a simple design of broadband tunable metamaterial absorber (MMA) in the terahertz (THz) region, which consists single layer complementary gammadion-shaped (CGS) graphene sheet and polydimethylsiloxane (PDMS) dielectric substrate placed on continuous metal film. The Fermi energy level (Ef) can be modulated dynamically by applied DC bias voltage, enables us to electrically control absorption performance proposed MMA flexibly. When Ef = 0.8 eV, relative bandwidth MMA, represents...
Circular dichroism (CD) in terahertz (THz) regions has been widely used biomonitoring, analytical chemistry, communication sensing, and other fields. Herein, we present a simple design for dual-band THz chiral metasurface absorber (CMA) with stronger CD effect based on temperature-tunable InSb enhanced sensing applications. The proposed CMA consisted of periodic array the evolved C-shaped adhered to copper substrate. designed at 305 K achieved right-handed circular polarization...
In recent years, metasurfaces composed of lumped nonlinear circuits have been reported to exhibit the capability detecting specific electromagnetic waves, even when waves are same frequency, depending on their respective waveforms or, more precisely, pulse widths. Herein, three types metasurface absorbers (MSAs) presented which a square‐patch structure loaded with linear circuit components, including resistors or in parallel capacitors/inductors, can mimic waveform‐selective absorption...
