“…The expressions (5)(6) were used to calculate the τ i values for structure 1 of the reflection symmetric MF (Figure 6a) with the parameters obtained after multicriteria optimization. The results of calculating τ i using the TALGAT software and analytical expressions are compared in Table 8.…”

“…Note that as the structure is symmetric (Figure 6a) with respect to the vertical and horizontal axes, the diagonal elements of matrix A are the same a 11 = a 22 = a 33 = a 44 and there is a pairwise equality of elements outside the main diagonal (a 12 = a 34 and a 13 = a 24 ). Finally, matrix A turns out to be symmetric, since it is a product of symmetric and commutative matrices L and C: In addition, by simplifying expressions (5,6), it is possible to obtain analytical expressions in a short form for the reflection symmetric MF:…”

“…Particularly, it is important to protect computers from interference originating in power lines [4]. Recent investigations have shown the possibility of interrupting the normal functioning of IT networks through high-power electromagnetic interference via the power lines [5] and the local area network cables [6]. The analysis of the impact of a commercially available powerful source of damped sinusoids on a computer network was presented in [7].…”

The paper considers the protection of critical radio-electronic equipment (REE) from ultrashort pulses (USP) by means of modal filters (MFs). A new approach to improve modal filtration by using reflection symmetry is analyzed. The results of a sophisticated research into protective devices based on reflection symmetric MFs are presented: improving the characteristics of four MFs through optimization both by one and simultaneously by several criteria; calculating the per-unit-length time delays matrix of a reflection symmetric MF using the obtained analytical expressions; calculating the time and frequency responses of an MF with and without losses in conductors and dielectric; developing the laboratory evaluation board; analyzing the effect of moisture protection on the characteristics; analyzing the features of reflection symmetry structures; comparing microstrip and reflection symmetric four-conductor MFs. The obtained results allow us to argue that the reflection symmetric MF protects REE from a USP due to its decomposition into a sequence of pulses with pairwise equalized voltage amplitudes and close time intervals between decomposition pulses with an attenuation coefficient of four times with a controlled bandwidth of a useful signal. This research helps take advantage of the possibilities of using the symmetry to improve modal filtering and opens the ways to create a large number of new MF designs, applying only the principles of the symmetry described in the work.

“…Therefore, the perceived effects are not linked to the physical processes on the network cables or within the computers. In van Leersum (2013) and Kreitlow et al (2014) it was shown that an observed drop of the transmission speed can be a result of the control algorithms, although the physical degradation of the network is not very strong.…”

Abstract. Ethernet connections, which are widely used in many computer networks, can suffer from electromagnetic interference. Typically, a degradation of the data transmission rate can be perceived as electromagnetic disturbances lead to corruption of data frames on the network media. In this paper a software-based measuring method is presented, which allows a direct assessment of the effects on the link layer. The results can directly be linked to the physical interaction without the influence of software related effects on higher protocol layers. This gives a simple tool for a quantitative analysis of the disturbance of an Ethernet connection based on time domain data. An example is shown, how the data can be used for further investigation of mechanisms and detection of intentional electromagnetic attacks.
