Stability analysis of the self-phase-locked divide-by-2 optical parametric oscillator [PDF]

, 2005
The properties of all-optical phase-coherent frequency division by 2, based on a self-phase-locked continuous-wave (cw) optical parametric oscillator (OPO), are investigated theoretically.

An Unequal Power Divider with Adjustable Dividing Ratio

The Journal of Korean Institute of Electromagnetic Engineering and Science, 2007
In this paper, an unequal 1:N Wilkinson power divider with adjustable dividing ratio is proposed. The proposed unequal power divider is composed of basic Wilkinson structure. It consists of rectangular-shaped defected ground structure (DGS), isolated island pattern in DGS, and varactor diodes of which capacitance depends on bias voltage.

Compact Band-Selective Power Divider Using One-Dimensional Metamaterial Structure

International Journal of Antennas and Propagation, 2019
A band-selective power divider is demonstrated for the first time. By replacing lumped element right-handed (RH) and left-handed (LH) transmission lines (TL) in a conventional Wilkinson power divider, it is possible to achieve both power division and ...

Microwave Slow-Wave Structure and Phase-Compensation Technique for Microwave Power Divider [PDF]

, 2014
In this paper, T-shaped electromagnetic bandgap is loaded on a coupled transmission line itself and its electric performance is studied. Results show that microwave slow-wave effect can be enhanced and therefore, size reduction of a transmission-line ...

Recursive Active Filter with Metamaterial Unequal Wilkinson Power Dividers [PDF]

, 2010
In this work, it is shown that it is possible to implement an unequal Wilkinson power divider with reduced dimensions by using metamaterial transmission lines based on complementary split ring resonators (CSRRs), in planar technology.

Resistive Threshold Logic

, 2013
We report a resistance based threshold logic family useful for mimicking brain like large variable logic functions in VLSI. A universal Boolean logic cell based on an analog resistive divider and threshold logic circuit is presented.

Design of Length-Saving Multiway Wilkinson Power Dividers

IEEE Access, 2018
A conventional multiway Wilkinson power divider must include transmission lines with a quarter of the wavelength. The prior miniaturized versions can further shorten the quarter-wave lines by adopting synthesized transmission lines, but the resulted ...

A meandered dual-band power divider with improved performance for wireless applications using a neural network inverted model

Next Energy
In this paper, a dual-band Wilkinson power divider is presented using open-stubs and meandered lines. The first operating frequency of this divider is 2 GHz, and the second operating frequency is 4 GHz.

Electro-expulsive separation system [PDF]

, 1987
An electro-expulsive system has one or more overlapped conductors, each comprising a flexible ribbon conductor, which is folded back on itself. The conductors are embedded in an elastomeric material.

Invariants in divided power algebras

Journal of Algebra
Let $k$ be an algebraically closed field of characteristic $p>0$, let G=GL_n be the general linear group over $k$, let g=gl_n be its Lie algebra and let $D_s$ be subalgebra of the divided power algebra of g^* spanned by the divided power monomials with exponents $1$.
