The set of electric field (E) and magnetic field (H) associated to the same conductor is called electromagnetic field and, when the whole system of fields travel, it is said that or an electromagnetic wave or radiation exist. Within an aircraft all causes of disturbances occur adding same equipment inside and which that can be included because of the ...

Characteristics of Power Cable Shielding
Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 1960WITHIN the past few years, there have been a number of interesting papers relating to the characteristics of power cable shielding, covering both theoretical and experimental work being done in this field. At the laboratory of the Simplex Wire & Cable Company, it was felt that added knowledge of the phenomena involved might be obtained if experiments ...

Shielding Performance of Triply Shielded Coaxial Cables
IEEE Transactions on Electromagnetic Compatibility, 1980We determine the shielding effectiveness of a triply shielded coaxial cable and compare it to the performance of a singly shielded cable. Then we apply well-known transmission-line theory to make a parametric study of the shielding performance as a function of the geometrical and electrical parameters of the braids. We suppose that the three braids are

Cable Shielding Effectiveness Testing
IEEE Transactions on Electromagnetic Compatibility, 1974This paper discusses an improved method of measuring the effectiveness of cable shielding and describes the results of tests on single- and multi-branched cables. Effects of significant shielding parameters of cables are also reported. These are the the effect of number of shield braid layers, braid material, braid angle, optical coverage, cable length,

A FEM approach to shielding effectiveness in braided-shield cables
IEEE Transactions on Magnetics, 1990The coupling between an electromagnetic field and a braided-shielded cable is analyzed using a numerical approach. Penetration of the magnetic field through the shield and apertures is described by the homogeneous Helmholtz equation in terms of the magnetic vector potential.

EMP coupling through cable shields
IEEE Transactions on Antennas and Propagation, 1978Recent research in electromagnetic coupling between the interior and exterior of coaxial cables is described. Both tubular shields and shields with apertures are discussed with reference to the physical coupling mechanisms and their mathematical representations in terms of transmission-line models.

Iron Shielding for Telephone Cables
Transactions of the American Institute of Electrical Engineers, 1934Among the benefits obtained by the cabling of telephone circuits is the substantial reduction in magnetically induced voltages that can be realized from the shielding action of the lead sheath. Even greater shielding is attainable if the cable is provided with a steel armor or is installed in conduit. In this paper is preiron pipe conduit.

Analysis of the emittivity of a chirally shielded cable
Proceedings. Asia-Pacific Conference on Environmental Electromagnetics. CEEM'2000 (IEEE Cat. No.00EX402), 2002The analysis of the emittivity of a chirally shielded cable is presented. An E-polarized cylindrical wave, coming from the centre of the cylinder, incides onto the chiral medium resetting in a coupling between TM/sup z/ and TE/sup z/ waves. The analytical expression of the shielding effectiveness in order to evaluate the emittivity has been derived and
