Poisson's equation is solved to obtain the potential distribution in the cross section. The horizontal and vertical components of the electric field are computed from the gradient of the solution. The field variation below the septum are computed and their variations are plotted. The uniform region of the vertical component of electric field is found and isolation of the horizontal component of electric field is determined.. This proves that in the region below the septum the TEM cell supports uniform transverse electromagnetic (TEM) field, which is a requirement for testing the susceptibility levels of electronic equipment.","PeriodicalId":148043,"journal":{"name":"Proceedings of the International Conference on Electromagnetic Interference and Compatibility (IEEE Cat.

The most important feature is the reduction in weight of the structure compared to other alternatives. Majority of the material systems of this class with the exception of carbon fiber based composites, are also transparent to EM radiation. There are applications where such structural composites should not transmit EM radiation while retaining the weight advantage. The present study investigates the effect of the inclusion of a metallic (Al, Cu) foil, metallized fabric on the EM transparency of such composite material systems. Sample laminated plates following the above scheme were subjected to shielding effectiveness test using EMI/EMC test facilities in accordance with MIL STD 285. Results have indicated effective EM shielding in the frequency range of 20 MHz to 10,000 MHz when metallized fabric, Cu foil and Al foil were used in that order.","PeriodicalId":148043,"journal":{"name":"Proceedings of the International Conference on Electromagnetic Interference and Compatibility (IEEE Cat.

Miniaturization of equipment structures as well as increasing complexity of electronic circuitry, their integration and interconnections makes all electric installations and components vulnerable to such EMI disturbances. Conducted interference is one of forms of subject EMI disturbances, which normally exists due to sharing of power bus between different circuits or systems or equipment. Such conducted EMI usually travel normal current paths of electronic equipment and can provide potential impact on its operational states. Often EMI currents are produced due to inadequate EMI design considerations within the equipment. Situations like these, demand the control/reduction of such conducted EMI preferably at design stage. The author in this paper highlights noncompliance of lighting appliances (i.e. electronic ballasts with compact fluorescent lamp load) with applicable conducted regulatory limits. Apart from the analysis part, this paper also deals with remedial measures taken in appliances, which finally leads to compliance with conducted regulatory limits.","PeriodicalId":148043,"journal":{"name":"Proceedings of the International Conference on Electromagnetic Interference and Compatibility (IEEE Cat.

The problems come mainly from various emitters situated in the same network or from other networks in the vicinity of sensitive receivers. After the network is established and is working for some time, suddenly a new interference can crop up due to repair or change of location of an existing system or induction of a new system in the network. In LRDE we have developed a package to address some of these problems. The paper highlights the existing features of this software tool, its GUI features, merits, shortcomings and the way AI features can be incorporated into this software for handling complex EMI situations in the network.","PeriodicalId":148043,"journal":{"name":"Proceedings of the International Conference on Electromagnetic Interference and Compatibility (IEEE Cat.

It is also highly amenable to automation. Here, a numerical solution based on third-order C/sup 1/ triangular finite element is proposed for solving 2D electromagnetic field problems. The design of this new finite element involves field variable and its derivatives as degrees of freedom compared to the standard Lagrangian polynomial based finite element available in the literature. The performance/effectiveness of the present method is studied against that of standard element. For almost same accuracy, the number of equations to be handled based on present formulation reduces to less than half of those of standard element, which, in turn, leads to significant saving in CPU time and memory requirements.","PeriodicalId":148043,"journal":{"name":"Proceedings of the International Conference on Electromagnetic Interference and Compatibility (IEEE Cat.
