Dual-Polarized Band-Notched Antenna Without Extra Circuit for 2.4/5 GHz WLAN Applications
IEEE Access, 2019 In this paper, a dual-band dual-polarized crossed dipole antenna with good anti-interference capability is proposed for 2.4-/5-GHz WLAN applications. The proposed antenna covers the WLAN 2.4-GHz band (2.4-2.48 GHz) and 5-GHz bands (5.15-5.85 GHz) with ...

Measurement of radio emission from extensive air showers
, 2009 A new promising development in astroparticle physics is to measure the radio emission from extensive air showers. The particles in the cascade emit synchrotron radiation (30 - 90 MHz) which is detected with arrays of dipole antennas.

Advanced Functional Materials, EarlyView.Electrochemical CO2 reduction (ECR) to formate is a promising route for sustainable chemical production. Herein, we report the synthesis catalysed byBi‐HfO2@C. The AIMD simulations, DFT calculations, and in situ SEIRAS measurements show that the modification of HfO2 on the Bi surface steers the interfacial water to adopt a favorable hydrogen‐down (OH2↓)

Advanced Functional Materials, EarlyView.Charge transport in 2D tin perovskite FETs is shown to be governed by dielectric interface behavior. Polar polymer dielectrics induce dipolar disorder that localizes carriers, whereas nonpolar polymers suppress trapping and enable superior charge transport, ensuring stable and reliable transistor operation. ABSTRACT Understanding the role of interfaces

Q factors for antennas in dispersive media [PDF]
, 2014 Stored energy and Q-factors are used to quantify the performance of small antennas. Accurate and efficient evaluation of the stored energy is also essential for current optimization and the associated physical bounds. Here, it is shown that the frequency
