Design and Analysis of Microstrip Antenna Arrays in Composite Laminated Substrates  [PDF]
S. M. Yang, C. H. Huang, C. C. Hong
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2014, DOI: 10.4236/jemaa.2014.66011
Abstract:

In high performance aerospace systems where weight and aerodynamics are of major concern, fiber reinforced composite laminates can be tailored to achieve desirable mechanical properties and accommodate low-profile microstrip antenna. This work aims at the analysis of microstrip antenna array embedded in composite laminated substrates. The size of a single antenna is first calculated by spectral domain analysis to model the effects of the substrate’s electromagnetic property and the orientation of the laminate layers. The antenna array as well as the feed network, composed of microstrip transmission lines, quarter wave-length impedance transformers, and T-junction power dividers, is then tuned to accommodate the effects of the coupling between the antenna elements and the feed network loss. The performance of the 1 × 2, 1 × 4, and 1 × 8 linear array and 2 × 2 and 2 × 4 planar array are shown to have better directivity when embedded in composite laminated substrate compared with those when attached on isotropic substrate. Both 1 × 2 and 1 × 4 arrays at 2.4 GHz are validated experimentally to achieve better coverage.

Observation of B -> phi phi K

Physics , 2003, DOI: 10.1103/PhysRevLett.91.241802
Abstract: We report the observation of the decay mode B -> phi phi K based on an analysis of 78 fb^{-1} of data collected with the Belle detector at KEKB. This is the first example of a b -> s sbar s sbar s transition. The branching fraction for this decay is measured to be B(B^{+-} -> phi phi K^{+-}) = (2.6 ^{+1.1}_{-0.9} +- 0.3) x 10^{-6} for a phi phi invariant mass below 2.85 GeV/c^2. Results for other related charmonium decay modes are also reported.
Rare B Decays at Belle

Physics , 2002,
Abstract: Recent results of rare B decay analyses based on 31.9 million $B\bar{B}$ collected with the Belle detector at the KEKB asymmetric $e^+e^-$ collider are presented. We have made the first observation of charmless baryonic decay $B^\pm \to p \bar{p} K^\pm$, the three-body $B^0 \to K^0 \pi^+ \pi^-$ and $B^0 \to K^0 K^+ K^-$. The measured branching fractions are $\mathcal{B}(B^+\to p \bar{p} K^+) = (4.3^{+1.1}_{-0.9} \pm 0.5)\times 10^{-6}$, $\mathcal{B}(B^0{\to}K^0\pi^+\pi^-) = (\brkspp) \times 10^{-6}$, and ${\mathcal{B}}(B^0{\to}K^0 K^+ K^-) = (\brkskk) \times 10^{-6}$. We also see strong evidence of $B^\pm \to \eta K^\pm$ and $B^\pm \to \eta \pi^\pm$, and observed the decay $B^\pm \to \omega K^\pm$ with $\mathcal{B}(B^\pm \to \omega K^\pm) = (9.9^{+2.7}_{-2.4} \pm 1.0) \times 10^{-6}$. Preliminary results of improved measurements of the branching fractions for the decays $B \to K \pi$ and $\pi \pi$ are reported. No evidence for direct CP violation is found in the decays $B^\pm \to K^\pm \pi^\mp$, $K^\pm \pi^0$, $K^0 \pi^\pm$, $\pi^\pm \pi^0$, and $\omega K^\pm$.
High Density out-of-Plane Microprobe Array
Huang C. H. Huang C. H.,Chingfu Tsou,Tenghsien Lai
Computer Science , 2008,
Abstract: MEMS technology has been developed rapidly in the last few years. More and more special micro structures were discussed in several publications. However, all of the structures were produced by consist of the three fundamental structures, which included bridge, cantilever and membrane structures. Even the more complex structures were no exception. The cantilever with the property of simple design and easy fabrication among three kinds of fundamental structure, therefore, it was popular used in the design of MEMS device.
