In fact, providing the required power to the different IC's at the specified noise-free voltage levels allows a correct functioning of the overall PCB systems. More over, the ongoing trend of replacing active devices with peripherally located I/O and PWR/GND pins with areally located I/O and PWR/GND pins (BGA packaged) increases the complexity of the models, when power delivery issues need to be studied in a larger contest, such as the overall PCB's. The employment of the powerful, but simple, concept of the segmentation method allows investigation of the power delivery network of the PCB systems in two fundamental stages. During the first stage, a small cut out of the board corresponding to the BGA footprint is modelled with a 3D full wave simulation tool. During the second stage the equivalent impedance network representation corresponding to this cut out is combined, by means of the segmentation method, with larger pieces of a board, whose network representations can be extracted from the closed form expression of the cavity model approach","PeriodicalId":6459,"journal":{"name":"2005 International Symposium on Electromagnetic Compatibility, 2005.

For the temperature analysis, FDTD method is used to analyze electromagnetics and SIMPLE (semi-implicit method for pressure linked equations) method is used for calculation of heat transport and air convection enabling to analyze local heat transfer more strictly than heat transport equation (HTE) method which is the traditional heat transport analysis method. And we propose four types of wave absorbers to analyze these temperature distribution on the resistive film to find the best type with least temperature rise. As a result, when glass and metal plates are used for spacer and reflector, respectively, the absorber proved to be the best one from a view point of temperature descent. And it is shown that the temperature range does not cause the change of absorbing characteristics in the analysis but the temperature rise exceeds 160 degC, the characteristics may change","PeriodicalId":6459,"journal":{"name":"2005 International Symposium on Electromagnetic Compatibility, 2005.

We propose a novel method of calibrating the EMI antenna using a reverberation chamber. When two antennas are placed opposite each other in an ideal reverberation chamber, the mean value of the complex received value equals the free-space propagation loss between them because the vector sum of the reflected waves with random phases is zero. Therefore, the free-space antenna factor can be determined from the mean value of the complex received value.

The L-shaped bridge design on the FSS power plane not only broadens the stop-band bandwidth, but also increases the mutual coupling between the adjacent FSS cells with allowing the significant decrease of the gap between the cells. It is found the small gap design can ease the degradation of the signal quality for the signal referring to the perforated FSS power plane. The excellent SSN suppression performance with keeping reasonably good signal integrity for the proposed structure is validated both experimentally and numerically. Good agreement is seen.","PeriodicalId":6459,"journal":{"name":"2005 International Symposium on Electromagnetic Compatibility, 2005.

Then, the resultant macromodel and equivalent current source are ready to be synthesized into SPICE-compatible circuit simulator to efficiently expedite the transient analysis of the hybrid interconnects and lumped circuit elements with the external electromagnetic interference. Numerical example exhibits that this systematic approach is a computationally efficient method to solve the electromagnetic susceptibility problems, in which the external electromagnetic interference effects are fully considered.","PeriodicalId":6459,"journal":{"name":"2005 International Symposium on Electromagnetic Compatibility, 2005.

Evaluations based on simple statistics and a 2D feature selective validation (FSV) analysis are presented. Statistical differences between the measurements and simulations are found be better than /spl plusmn/3 dB (which is also the estimated uncertainty of the measurements) for more than 83% of the sampling points, depending on the measurement plane. These conclusions are also supported by the 2D FSV analysis. Taking account of measurement uncertainties, results are judged to be \"ideal\", in terms of the similarities between the amplitudes of the normalized spatial field distributions, and \"very good\" in terms of the similarities between the shape and locations of features. The study confirms that satisfactory accuracy can be gained in the prediction of field distributions due to vehicle mounted antennas. Using the 2D FSV approach, comparisons between the two antenna configurations are more similar than statistical measures, which are based on amplitude alone, would suggest.","PeriodicalId":6459,"journal":{"name":"2005 International Symposium on Electromagnetic Compatibility, 2005.
