The characteristic impedance of a power line is an important parameter in power line communication (PLC) technologies. This parameter is helpful for understanding power line impedance characteristics and achieving impedance matching. In this study, we focused on the characteristic impedance matrices (CIMs) of the medium-voltage (MV) cables. The calculation and characteristics of the CIMs were investigated with special consideration of the grounded shields and armors, which are often neglected in current research. The calculation results were validated through the experimental measurements. The

AbstractIn this paper, the characteristic impedance matching of the inner line and outer line of the multi-filar tape-helix Blumlein pulse forming line (BPFL) is analyzed in detail by dispersion theory of tape helix. Analysis of the spatial harmonics of multi-filar tape-helix BPFL shows that the integer harmonic numbers of the excited spatial harmonics are not continuous. In addition, the basic harmonic component still dominates the dispersion characteristics of the multi-filar tape-helix BPFL at low frequency band. The impedance mismatching phenomenon caused by the discontinuity of filling di

This work examines the feasibility of designing an impedance synthesis network based on a double-ridge waveguide (DRW). This design is based on the concept of the stepped-impedance line transformer as a cascade of transmission lines with different characteristic impedances, but using, in this particular case, a stepped-ridge waveguide. It is shown that this structure is able to synthesize not only real impedances but an arbitrary impedance, following some restrictions explained in this paper. An impedance synthesis network based on DRW can have numerous applications, like being used in designi

Two-microphone impedance tubes are a popular method to measure the normal incidence sound absorption coefficient. However, a single measurement with this method does not offer enough information to identify the sound propagation characteristics, i.e. the characteristic impedance and the wave number of absorbent samples. Instead, more elaborate measurement techniques that require more time, more equipment and enhanced user knowledge need to be applied. This contribution presents a technique combining neural networks and the two-microphone impedance tube method to estimate the propagation charac

Abstract In Active Distribution Network (ADN), T-connection transmission lines are formed when Distributed Generations (DGs) are connected to transmission lines rather than to buses. In the T-connection transmission line with DG, the pilot current differential protection loses selectivity due to the change of fault current caused by T-type connection DG. Differential current increases to as much as the injected DG current when an external fault occurs, which results in maloperation. The impedance differential protection using measured impedance characteristics can effectively distinguish the f

An infinitesimal constant was used to replace 0 Hz frequency to calculate the DC and AC part of input impedance simultaneously. The input impedance at any point of the arterial tree can obtain easily by the proposed recursive algorithm. The results of input impedance are in accord w

We propose new empirical expressions for the characteristic impedance of a microstrip-like interconnect line in presence of ground plane aperture. The existing characteristic impedance expressions are modified so as to include the effect of the ground plane aperture. The variation in the characteristic impedance vis-à-vis the aperture size is established. The proposed expressions are general and valid for a range of dielectric materials concerning MICs, RFICs, and PCBs. The results are validated by measurements performed on a vector network analyzer.

We investigated the effect of changing arterial input impedance over three selected frequency ranges on stroke volume (SV) in nine isolated canine left ventricles. The input impedance was simulated with a three-element Windkessel model (i.e., resistance, characteristic impedance, and compliance) and was imposed on the ventricles with a servo-controlled loading system. Under a constant end-diastolic volume [33.1 +/- 1.5 (SE) ml], we changed the modulus of the afterloaded impedance over a low frequency range (below 0.13 Hz) by changing the resistance, over a transitional frequency range (in whic

Background Systemic vascular resistance incompletely describes left ventricular afterload because of the phasic nature of arterial pressure and blood flow. Aortic input impedance is an experimental description of left ventricular afterload that incorporates the frequency- dependent characteristics and viscoelastic properties of the arterial system. The effects of propofol on aortic input impedance were examined using three variables derived from the three-element Windkessel model: characteristic aortic impedance, total arterial compliance, and total arterial resistance.
