This method reduces the numerical complexity of both memory requirement and matrix-vector multiplication of integral equation with asymptotically smooth kernels. The method does not require explicitly the knowledge of the integral kernel and therefore can be integrated into existing boundary integral equation (BIE) and/or MoM codes easily. This paper extends the ACA to oscillatory integral kernel and applies it to the ground plane designs. We have demonstrated through numerical examples that for moderate-sized problems (less than few hundred thousand unknowns) the multilevel ACA algorithm is still very effective and reliable for computer modeling of electromagnetic radiation and scattering problems.","PeriodicalId":378094,"journal":{"name":"2004 International Symposium on Electromagnetic Compatibility (IEEE Cat.

A method of calculating coupling with EMI capacitors is presented. The method is verified by experimental results. The presented results prove the possibility of simulating field coupling in circuits including the circuit's components. In particular, when miniaturizing power electronic devices, the calculated coupling among conductors and components must be taken into account to ensure EMC at the system level.","PeriodicalId":378094,"journal":{"name":"2004 International Symposium on Electromagnetic Compatibility (IEEE Cat.

This paper discusses the increasing difficulties caused by the masking of EMI emissions by new ambient threats at the OATS. The characteristics of ambients are analyzed and recommendations given for EMI measurements in the presence of the more common OATS ambients. Ambient profiles of old and new OATS are compared and the changes discussed. It is shown that validity of OATS in high ambient urban areas is questionable.","PeriodicalId":378094,"journal":{"name":"2004 International Symposium on Electromagnetic Compatibility (IEEE Cat.

With the introduction and deployment of new technologies comes the need for new regulatory requirements.

Finally, the antenna factor of the quadruple-gap loop antenna is directly compared with theoretical formulations.

For an applied pulse having a duration that was sufficiently short compared to the shield response, the transient electric field response approached a result that depended on the total charge transported along the surface of the cylinder during the applied current pulse but was essentially independent of the particular time variation of the applied pulse. For practical purposes, such pulses can be regarded as impulses, and the resultant electric field response can be regarded as an impulse response for that charge level. Experimental results for a wide range of injected charge levels on a mildly ferromagnetic specimen are presented. Unlike the impulse response for the linear problem with a constant permeability, the impulse response exhibits nonlinear variation with applied charge level.","PeriodicalId":378094,"journal":{"name":"2004 International Symposium on Electromagnetic Compatibility (IEEE Cat.
