A simulation technique based on electromagnetic topology EMT theory is proposed for analyzing electromagnetic interference EMI coupling through apertures onto the two-transmission line enclosed within metallic structures. The electromagnetic interactions between apertures and the external-internal interactions were treated through the topological decomposition and the multistep iterative method...

Abstract This paper presents wavelet based analysis for transmission line fault location. Faults in power transmission lines cause transients that travel at a speed close to the speed of light and propagate along the line as traveling waves (TWs). Traveling wave theory is utilized in capturing the travel time of the transients along the monitored lines between the fault point and the protective...

The main aim of this paper is to detection and classifies the various types of ground and line faults in transmission line. A new current decomposition is proposed in order to derive the positive, negative and zero current components. The faults may be an insulation failure of conductors and cables, lightning or accidental faulty operation of any connected equipment. In a transmission line dete...

ABSTRACT In this study, bifurcation and complex phenomena in synchronizing chaotic oscillators coupled by a lossless transmission line are investigated. The period-doubling bifurcation with varying the time delay is observed in our circuit model. Further the voltage distribution of transmission line is simulated in order to investigate whether the current flowing through the transmission line i...

Optical-fiber transmission of pulses can be modeled with the complex Ginzburg–Landau equation. We find novel stable soliton pairs and trains, which are relevant in this case, and analyze them. We suggest that the distance between the pulses and the phase difference between them is defined by energy and momentum balance equations, rather than by equations of standard perturbation theory. We pres...

A veriication of calculated electrical parameters of transmission lines on printed circuit boards is presented. Furthermore, the innuence of common manufacturing processes on the principle cross section of transmission lines and the resulting electrical parameters is subject of the investigations. With regard to existing manufacturing tolerances a sensitivity analysis is carried out taking acco...

Most of the published theory on the optimal performance of decision-feedback equalization under the MMSE criterion addresses the transmission of i.i.d. symbol sequences only. This paper presents a theory which accommodates the case of correlated symbol sequences. It also considers the use of a fractionally spaced forward filter in the decision-feedback equalizer (DFE). Two limiting conditions a...

The main purpose of the paper is to summarize some fundamental results concerning the matrix impulsive differential equations with impulses at fixed points. The theory of impulsive matrix differential equations is interesting in itself and it will assume greater importance in the near future, since the application of the theory to various fields of science is also increasing, especially in the ...
