The approach is based on new concept of modal filtering used jointly with known filtering principles. Some preliminary results of the approach implementation are presented. Particularly, the difference of per unit length modal delays for various types of cables and PCB interconnects is calculated. It is shown that the difference can be around 1 ns/m, while for special structures can be increased up to 5 ns/m. It allows, for example, for 1 m interconnects the modal filtration against ultra wideband pulses shorter than 1 ns and 5 ns.","PeriodicalId":397061,"journal":{"name":"2007 18th International Zurich Symposium on Electromagnetic Compatibility","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116679568","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 shown that dividing a specified area into a combination of multiple apertures may reduce the value of the radiated emissions and therefore improve the shielding effectiveness.

Closed-form expressions for the reflection coefficient, the relative deviation in field and the relative error in induced current caused by the reactive effect of the cell are derived. Each of these expressions encompasses both the mutual influence of the DUT’s RCS and the reactive effect of the cell. It is shown that, depending on the frequency dependent phase factor ejͨ, strong and weak test conditions may occur since the overall incident field will exhibit maxima and minima. Hence evidence showing that the total incident field impinging on the DUT generally deviates from the primary excited TEM field is provided.","PeriodicalId":397061,"journal":{"name":"2007 18th International Zurich Symposium on Electromagnetic Compatibility","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125473095","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}

This method facilitates EMC-compliant eletronic design. As an example, it is used to virtualize the BCI test method. It can also be applied to e.g. the stripline method. The required SPICE models of the components of the measurement setup are generated just once. They are based on scattering parameter measurements. These measurements are made with real RF components of the BCI test setup. In a schematic the SPICE models and the test circuit are connected according to the real test setup. At first in an AC analysis all voltages and currents are simulated by modelling the BCI clamp as an AC source with a constant stimulus of one volt. During real measurements a control computer sets the frequency-dependent amplitude of the generator. For this process, the standard DIN ISO 11452:4 specifies two test conditions: “open loop” and “closed loop”. In the virtual immunity test, all simulated voltages and currents due to the one volt stimulus are linearly scaled in order to match the real conditions using a computer-controlled frequency-dependent RF test power. This virtual test method makes the development process faster and cheaper.","PeriodicalId":397061,"journal":{"name":"2007 18th International Zurich Symposium on Electromagnetic Compatibility","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128794694","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}

For MR guidance of vascular interventions to be safe, the interventionalist must be able to visualize catheters and guidewires relative to the vascular system and surrounding tissues. A number of approaches for rendering instruments visible in an MR environment have been developed, including both passive and active techniques. Passive techniques depend on contrast agents or susceptibility artifacts which enhance the appearance of the catheter in the image itself, whereas active techniques rely on supplemental hardware built into the catheter, such as a radiofrequency (RF) coil (Fig. 1). The additional capabilities of MRI could potentially open up new applications within the purview of vascular interventions beyond those currently performed under X-ray fluoroscopic guidance. This presentation will review some requirements for performing interventional cardiovascular MR procedures, preclinical studies as well as issues of MR safety related to interventional devices.","PeriodicalId":397061,"journal":{"name":"2007 18th International Zurich Symposium on Electromagnetic Compatibility","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129016674","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}
