Time domain analysis methods however have the disadvantage of being significantly more complex and requiring much longer solution times than frequency domain analysis methods. Conventional methods for time domain waveguide analysis include the finite difference time domain method and the method of moments. Intermediate level circuit modeling methods have been shown to be far more efficient than these conventional methods. A novel equivalent circuit of a waveguide section suitable for intermediate level circuit modeling is proposed that has the advantage of being easier and quicker to formulate, and requires significantly less time to reach a solution than conventional time domain methods. The time domain solution is arrived at by utilizing a circuit simulator (SPICE) to analyze the intermediate level circuit for waveguide sections. Results obtained using the proposed circuit in SPICE were found to be credible when compared to known analytical results.","PeriodicalId":359422,"journal":{"name":"2003 IEEE Symposium on Electromagnetic Compatibility.

Their ability to sustain the interference from each other is susceptibility. It is important to find which levels of interference disrupt the normal operation of those devices. Is a portable television monitor sensitive to the interference from other electronic equipment operating at the same frequencies? What are the signal levels that will cause the interference? To solve this problem, a GTEM-cell structure was used. It has homogeneous electromagnetic field area where the equipment under test is placed. Finite element method is used to model the loaded and unloaded GTEM-cell. The interference is measured using the signal generator, Hewlett Packard 8640B and Tektronix CFG250 function generator. The insertion of the TV monitor changes the electric from 2.25 to 1.25 mV/m, so the measured results must be calibrated. The sensitivity is 97 dB [ /spl mu/V/m ] for lower frequency and dropping to 80 dB [ /spl mu/V/m ] for higher frequencies. Since they are higher than the C.I.S.P.R and FCC levels for radiated emissions for A and B class equipment at the test distance of 10 m, the tested TV monitor meets the standard requirements.","PeriodicalId":359422,"journal":{"name":"2003 IEEE Symposium on Electromagnetic Compatibility.

The key challenge is to develop techniques which provide a numerical output that do not challenge excessively the interpretations of experienced engineers and which presents both sufficient discrimination between comparisons and consistency across the various sub-disciplines of EMC. While this paper concentrates on the subject of numerical code generation, the rationale and associated concepts are just as relevant to other aspects of EMC such as quantifying experimental repeatability. The purpose of this paper is to present some of the work done to date on generating a numerical value representing the overall quality of comparison for two sets of data. This paper reviews and contrasts various techniques currently available to produce this numerical overview. The techniques include correlograms, feature selective validation (FSV), integrated error against log frequency (IELF) and reliability factors. The paper concludes that the most taxing aspect of the work required to develop such techniques is benchmarking against human interpretation, a rating scale is discussed which can assist in obtaining this information.","PeriodicalId":359422,"journal":{"name":"2003 IEEE Symposium on Electromagnetic Compatibility.
