Also presented, are the results from an experiment designed to test the model. The coupling of these exterior fields through a single elliptical aperture is approximated by the radiation from an equivalent dipole into the object. The magnetic moments for this dipole are determined by the physical size of the aperture. The screen is then modeled as a linear superposition of many individual aper tures. The total field at an interior point is calculated by summing the components of the fields from each of these apertures. In order to test this model, an aluminum cylinder was constructed to be used as a test object. This cylinder was the meters long with a diameter of one meter. The ends of the cylinder were tapered to provide a constant impedance at the terminations. The entire object was mounted in a multiple wire coaxial return path to provide a nominal 50 Ohm imped ance. The center section of the cylinder cylinder contained an aperture that was 1.5 m long and that extended along a circumferential arc of 120 degrees. Covers for this aperture were constructed using different sizes of expanded metal mesh. An impulsive current generator was used to inject currents axially onto the cylinder. The peak currents levels were up to 30 kiloamps (kA). The resulting magnetic fields across the screened aperture were measured and compared with the simul taneous fields at interior points.","PeriodicalId":443616,"journal":{"name":"1987 IEEE International Symposium on Electromagnetic Compatibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130015511","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 passive method utilizes thermal energy transmitted by an infrared-optical fiber, and the temperatures in question are caused by induced electromagnetic energy that is mainly in the microwatt ranges. Signal processing techniques are used to enhance the estimate of temperature caused by the induced energy. The proposed method also minimizes the effects of both coherent background noise and noise due to temperature variations along the length of the infrared-fiber. encountered with this technique is a slow system response time reported as approximately 70 ms. There is a possibility that thermal characteristics could be altered due to the method of sensing temperature. This system is still under study. This paper proposes a new method of measuring the induced currents in die EED's bridgewire. The method makes use of infrared optical fiber which reduces the uncertainties associated with the use of thermocouples to detect induced electromagnetic energy in the EED. The method reduces coherent noise in sensing bridgewire currents, and it also eliminates any appreciable thermal loading on the bridgewire. The response time of this experimental system is approximately 10 ms, and it can be lowered if required. The outline of the paper is as follows, the overall system is presented and discussed, the design criteria are discussed; and various system parameters are shown.","PeriodicalId":443616,"journal":{"name":"1987 IEEE International Symposium on Electromagnetic Compatibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129745730","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}
