IEEE Transactions on Microwave Theory and Techniques, 1970
This paper consists of two parts. In Part I, coupled-mode theory is employed to determine the effects of reflection at the various ports and unequal inductive and capacitive coupling coefficients on the coupling and directivity of two coupled lines.

On-line coupling of extraction with gas chromatography
Journal of Chromatography A, 2008A recent trend in the development of analytical methodologies is the integration of the sample preparation step directly with the chromatographic system. In integrated on-line systems, extraction, clean-up, separation and detection are connected with each other and the whole analytical procedure takes place in a closed, usually automated system.

The Design of Coupled Microstrip Lines
IEEE Transactions on Microwave Theory and Techniques, 1975Although graphical results and formulas are available for the design of microstrip couplers, the design procedure is hampered because even- and odd-mode impedances are always expressed in terms of the physical geometry. In practice the designer obtains these impedances and then requires to know the geometry given by them.

A new class of coupled-transmission-line directional couplers, called "nonsymmetrical directional couplers," is described. Unlike conventional directional couplers, nonsymmetrical directional couplers use coupled lines of unequal characteristic impedances.

Suppression of EM coupling spikes by line-shaping in high-speed coupled lines
IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002A line-shaping method in coupled data bus lines is demonstrated for suppressing the coupling spikes. Considering the fact that there are infinite number of possibilities for choosing coupled conductor line profiles, it is logical to ask if there is a profile which is best to suppress the crosstalk for a given physical/geometrical PCB configuration and ...

An Approximation to the Asymmetric Strip-Line Coupling Coefficient
IEEE Transactions on Computers, 1968Abstract—In the design of magnetic film memories and high-speed printed wiring systems, it is often necessary to estimate the coupling between adjacent conductors which are, in effect, strip lines with asymmetric ground planes. No solution to this problem exists in the literature. An heuristic approximation is found, and validated experimentally, which
