A bow-tie slot antenna with tapered connection to a 50Ω coplanar waveguide (CPW) feed line is introduced and its dimensional parameters have been studied for wideband operations in the X-band. A set of two element bow-tie slot antennas fed by one CPW is also introduced for wider bandwidth and improved gain. The configuration of one CPW feeding two elements of this antenna is simulated and it ac...

On-chip distributed transmission line resonators in CMOS technology have become the interest of research subjects recently (Ono et al. 2001; Umeda et al., 1994; Kanaya et al., 2006; Wolf, 2006) because of their size which becomes more compact, as the frequency of application increases. Among the various transmission lines, coplanar waveguide (CPW) has more engineering applications (Toyoda, 1996...

Femtosecond visible pump-IR probe studies of Cp2W2(CO)6 in P(OMe)3 and CH2Cl2 have allowed direct observation of a 19-electron intermediate and of disproportionation into CpW(CO)3- and CpW(CO)3P(OMe)3+ on the ultrafast time scale. A new disproportionation mechanism involving in-cage electron transfer between a 19-electron intermediate and a 17-electron radical has been proposed.

We designed and fabricated an electrically small antenna (ESA) with coplanar waveguide (CPW) matching circuit. Matching circuit is realized by using interdigital gap and transmission line. We designed ESA with the aid of the commercial three-dimensional electro magnetic field simulator. We also made experiments on the ESA with CPW matching circuits using patterned circuit board.

For more size reduction of the high temperature superconducting coplanar waveguide (CPW) bandpass filter (BPF), we introduce the design method of the meanderline CPW quarter-wavelength resonator BPF. The exact admittanceand susceptance-inverters are calculated by using the 2.5-dimensional electromagnetic field simulator. The prototype YBCO miniaturized BPF (center frequency =10GHz, n=3, band wi...

Development of hepatocellular carcinoma (HCC) is a multi-factorial process. Chronic infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) are important risk factors of HCC. Host factors, such as alcohol drinking, may also play a role. This study aims to provide a synthesis view on the development of HCC by examining multiple risk factors jointly and collectively. Causal-pie modeli...

To solve many of the problems encountered when using conventional coplanar waveguide (CPW) with its semiinfinite ground planes, a new version of coplanar waveguide with electrically narrow ground planes has been developed. This new transmission line which we call Finite Ground Coplanar (FGC) waveguide has several advantages which make it a better transmission line for RF and wireless circuits. ...

In order to improve the coverage and reliability of information perception layer power Internet things, a method constructing cross fusion network low-voltage line micro-power wireless communication (CPW) is proposed. Firstly, unified medium access control (MAC) model CPW established provide basic support for realizing integration layers; then an improved ant colony algorithm combining Brownian...

In this article, a new CAD model for the coplanar waveguide (CPW) cross-over air-bridge is proposed. The model takes into account the CPW open-end capacitance and the vertical strips of the bridge. The section directly underneath the bridge is modeled as a small section of a microstrip line. Our results are in good agreement with the published full-wave results. © 2005 Wiley Periodicals, Inc.

The Collaborative Partnership on Sustainable Wildlife Management (CPW) is a voluntary partnership of international organizations with substantive mandates and programmes for the sustainable use and conservation of wildlife resources. The mission of the CPW is to increase cooperation and coordination among its members and other interested parties on sustainable wildlife management to promote the...
