In this paper, we present the design, simulation, and measurement of a dual-band metamaterial absorber in microwave region.Simulated experimental results show that has two perfect absorption points near 11.15 GHz 16.01 GHz.Absorptions under different polarizations incident EM waves are measured with magnitude over 97% at low-frequency peak 99% high-frequency respectively.Current distribution dual absorptive peaks is also given to study physical mechanism power loss.Moreover, it verified by...
The design, fabrication, and measurement of a triple-band metamaterial absorber are presented. proposed consists metallic planar spiral layer ground plane separated by dielectric layer. Experimental results show that the can perform absorption peaks at three resonant frequencies 9.86 GHz, 12.24 15.34 GHz with 99.4%, 96.7%, 99.1%, respectively. In addition, thickness λ/35 lowest fundamental frequency operate wide range incident angles under both transverse electric magnetic polarizations.
An ultra-thin chiral metamaterial absorber (CMMA) is constructed from twisted 'L-shaped' folded metallic wires. In particular, it has high selectivity for left-handed and right-handed circular polarized (LCP RCP) incident waves, which impossible in traditional absorbers. The thickness of the CMMA only 0.8 mm, with absorption 93.2% LCP 8.4% RCP respectively. This superb performance can be applied homogeneous polarizers an arbitrarily wave polarization conversion efficiency. Meanwhile, current...

This proposed exhibits resonant transparency under linearly polarized incidence caused destructive interference between magnetic dipole and dipole. Notably, it also provides circular cross-polarization conversions left-handed circularly wave...
Ovarian cancer is usually treated with transurethral resection or systemic chemotherapy in clinic. However, the development of drug resistance ovarian frequently observed patients, leading to failure tumor inhibition and recurrence. In this study, we aimed efficiently reverse enhance anticancer effects by co-delivery chemotherapeutic agents multi-drugs resistant proteins inhibitor treatment.The cell viability was measured using MTT flow cytometry (Annexin V/PI staining) under different...
In this paper, a sensitive chirality selective metamaterial absorber (CSMA) is constructed by using 'I-shaped' resonator with asymmetric twisted metallic wires. Absorption of 95.18% and 91.77% at two resonant frequencies can be achieved for left-handed circularly polarized (LCP) incident wave, little loss right-handed (RCP) which results in significant absorptive circular dichroism. Not only the CSMA intensely absorb LCP illumination dual bands, but also (CP) conversion RCP wave over broad...
