In this paper, a novel broadband printed folded dipole RFID tag antenna with the artificial magnetic conductor (AMC) ground plane in UHF band is proposed. By introducing AMC ground plane, the RFID tag antenna shows great performance on the metal surface. The bandwidth of the proposed antenna ranges from 0.81GHz to 0.93GHz, which can cover both the China standard (840–845 MHz) and the FCC standard...
A fast and high-efficiency test approach for the complex permittivity characterization of flaky materials in UHF band is presented in this paper. A planar microstrip resonance sensor with two test ports is designed, simulated and optimized. In this approach,only two parameters are required to test for the determination of complex permittivity, namely, resonant frequency and 10dB bandwidth. Experimental...
Through introducing Koch fractal theory, an ordinary AMC structure and broadband Koch fractal AMC ground planes are designed and compared. The bandwidth and performance improvement of the fractal AMC ground plane are taken into consideration to acquire the low-profile antenna system at the frequency band from 40MHz to 70MHz. This research establishes the theoretical foundation for further experimental...
Through introducing Drude dispersion model, dispersion effects on electromagnetic characteristics of two kinds of invisibility cloaks are studied and compared. The near electric field distribution and the far field scattering are taken into consideration to acquire the discipline that dispersion affects the invisibility cloak. This research establishes the theoretical foundation for further experimental...
Induction of mutation and micronucleus (MN) formation by nitric oxide (NO) was investigated in mammalian cells using sodium nitroprusside (SNP) as a drug donor of NO. Results showed that the concentration of NO 2− in the tested solution rose according to time- and concentration-exposure to SNP. The treatment of SNP (0.5–8 μmol/ml with S9 or 2–8 μmol/ml without S9) induced a concentration-dependent...
