We consider a fading channel in which multiantenna transmitter communicates with multi-antenna receiver through reconfigurable intelligent surface (RIS) that is made of N passive scatterers impaired by phase noise. The beamforming vector at the transmitter, combining receiver, and shifts are optimized order to maximize signal-to-noise-ratio (SNR) receiver. By assuming Rayleigh (or line-of-sight propagation) on transmitter-RIS link RIS-receiver link, we prove SNR random variable equivalent...
A printed ultra‐wideband (UWB) antenna with five notched stop bands is presented. By introducing a pair of arc‐shaped slots, two defected ground structures and an open‐loop resonator, sharp notches are achieved at frequencies 2.4, 3.2, 5.2, 5.8 7.5 GHz. The proposed has been fabricated tested. measured results indicate that the design not only supports UWB bandwidth requirements but rejects narrow to avoid possible interference existing communication systems. In addition, relatively...
We report on the measurement of new low-lying states in neutron-rich 81,82,83,84Zn nuclei via in-beam γ-ray spectroscopy. These include 41+→21+ transition 82Zn, 21+→0g.s.+ and transitions 84Zn, 81,83Zn were observed for first time. The reduced E(21+) energies increased E(41+)/E(2+1) ratios at N=52, 54 compared to those 80Zn attest that magicity is confined neutron number N=50 only. deduced level schemes are three state-of-the-art shell model calculations a good agreement with all...
With the ever-increasing demand for high-speed and low-latency wireless communications, new generation of base stations, i.e., fifth (5G), has been deployed recently. However, this deployment raised growing concerns regarding potential public health implications associated with exposure to radio-frequency electromagnetic fields (RF-EMF). According type sources, RF-EMF can be catergorized into uplink (device-to-base station) downlink (base station-to-device) transmissions. In paper, we aim...
$\ensuremath{\beta}$-delayed one-neutron and two-neutron branching ratios $({P}_{1n}$ ${P}_{2n})$ have been measured in the decay of $A=84$ to 87 Ga isotopes at Radioactive-Isotope Beam Factory (RIBF) RIKEN Nishina Center using a high-efficiency array $^{3}\mathrm{He}$ neutron counters (BRIKEN). Two-neutron emission was observed $^{84,85,87}\mathrm{Ga}$ for first time were be ${P}_{2n}=1.6(2)%,1.3(2)%$, $10.2{(28)}_{\mathrm{stat}}{(5)}_{\mathrm{sys}}%$, respectively. One-neutron ratio...
A single-feed dual-band integrated circuit package antenna (ICPA) is reported. The ICPA, intended for use in either single-chip or single-package highly concurrent wireless receivers, implemented the format of a cavity-down ceramic ball grid array 15×15×1.9 mm3. Results show that ICPA achieved frequency ratio 2.2, return loss bandwidth 1.67% and gain −8 dBi at 2.4 GHz, 0.69% −2 5.25 GHz.
The very proton-rich 71 Kr isotope was produced through the in-flight fragmentation of 78 on a beryllium target at RIKEN – Nishina Center in order to study its β-decay properties. A stack double-sided silicon strip detectors, called WAS3ABi, used as decay station, where detection ion implants, β-decays and β-delayed protons took place. Beta-delayed γ-rays were measured using system 84 HPGe EURICA, surrounding station. main goal present precise measurement half-life Kr, literature there is an...
