An equivalent circuit model of the PDN is derived by using a recently-proposed conformal modeling technique, in which orthogonal meshes are used along with a treatment to improve the accuracy of the model. Since the conformal equivalent circuit model has a grid-like topology, it is suitable for direction-based algorithms such as an ADI method and the leapfrog ADI method. An advantage of the ADI-based method is that they can use a relatively-large time step size and reduce the total number of time steps in a transient simulation. In addition, the leapfrog ADI method is more efficient than the existing ADI method because its time marching procedure requires less updating processes. As a result, the conformal equivalent circuit model combined with the leapfrog ADI method can be accurate and efficient in modeling and analysis of the PDN.","PeriodicalId":412708,"journal":{"name":"2015 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132173683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since both discrete element parasitics and printed circuit board parasitics are included, the resulting models can be used to analyze the influence of these parasitics on voltage waveforms and emission spectra.

The input impedance is one of the most important parameters in LISN calibration. To measure the input impedance, an adapter is required to connect the Vector Network Analyzer (VNA) to the Equipment Under Test (EUT) port of the LISN. For test laboratories, it is of best interest to perform this calibration with high accuracy. Until now the impact of the adapter has not been clearly demonstrated theoretically. We present the design of an adapter and its associated modelling, a method for removing its impact from the measurement, the theoretical error on magnitude and phase input impedance.","PeriodicalId":412708,"journal":{"name":"2015 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131740776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is recommended that the EUT shall not exceed one-third of the distance between the floor and the septum in the TEM cell. It will be shown that for measuring isotropic responses of E-field probe (by rotating the probe under a constant incident field), even if the probe meets the one third requirement, the couplings between the probe and the TEM cell are non-negligible. As a result, the total E field inside the TEM cell varies during the rotation of the probe. In this paper, a novel compensation method is presented to remove the coupling effect. The method is based on recognizing the fact that the position of the E-field probe with respect to the TEM cell is periodic through the rotation of the probe. Electric field can be correlated to the rotational angle. Both theoretical analyses and experiment verifications are provided.","PeriodicalId":412708,"journal":{"name":"2015 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124680007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model is based on replacement of the complicated transmission line by an equivalent (in terms of the radiated field) single wire over ground plane.
