The results are compared to similar measurements obtained using the IEC 801-2 measurement method (1GHz bandwidth). Under contact discharge conditions, the wideband results indicate a risetime seven times faster than that reported using the IEC method and a peak current amplitude at least four times greater. EM1 generated by a contact discharge is shown to be a more severe threat to high speed telecommunications equipment than is the EM1 generated by an air discharge.","PeriodicalId":93568,"journal":{"name":"IEEE International Symposium on Electromagnetic Compatibility : [proceedings].

With impmved meawrement acciiracy, one of the major concerns of the EMC Community is the absolute accuracy of the field strength data that is compared to field strength specification limits for determination of equipment under test (EUT} compliance. Majab elements of the field strength value calculations are the anterm factors used in the computation of field strength. There is dependence for these values on traditional antenna calibration methods to adequately measure the antenna factor of EMC antennas. While each of the standard calibration procedures will produce adequate calibration results, any new method that provides separate verification or is a precise, accurate alternative method of measurement provides a new optinn for efficient determination of anteiuui factors. This pqer explores a new measurement methcl for antenna factors, provides comparative data and presents conclusions as to its adequacy.","PeriodicalId":93568,"journal":{"name":"IEEE International Symposium on Electromagnetic Compatibility : [proceedings].

In this paper, crosstalk or coupling between transmission lines in the arbitrary directions is studied by using a circuit concept. Under the condition of weak coupling, self-capacitances and self-inductances of the transmission lines can be approximated to be invariant in spite of existence of a proximate line. Mutual-capacitances and mutual-inductance is estimated by considering the coupling mechanism for an external electromagnetic field to a transmissicin line. To generalize our mode, a four-port network is also studied.","PeriodicalId":93568,"journal":{"name":"IEEE International Symposium on Electromagnetic Compatibility : [proceedings].

The model uses a conducting wire behind the openings rather than a farfield plane wave and predicts the received EM1 strength at typical FCC distances from these openings. The model allows overall dimensions of the vent, thickness of the vent, as well as number, spacing, and orientation of the holes to be varied. Rapid comparisons between existing and proposed slot lengths, air vent openings, and tolerance analysis are possible.","PeriodicalId":93568,"journal":{"name":"IEEE International Symposium on Electromagnetic Compatibility : [proceedings].

They are based on inter-metallic quantum mechanical tunnelling, have demonstrated higher speeds than other types of devices, and have the potential for achieving high energy per volume capacity, while being conformably moldable. The latter can yield a high degree of flexibility in device design allowing the coverage of a wide range of applications. This paper describes their principles of operation, examines the theoretical limit for energy handling in an ideal device, gives status of current material development as well as three potential application examples and their generic considerations.","PeriodicalId":93568,"journal":{"name":"IEEE International Symposium on Electromagnetic Compatibility : [proceedings].
