The penetration depth of electromagnetic fields at THz frequencies is less than 1 mm and thus substantially smaller than for radio frequencies. In addition, the short wavelengths in this frequency range cause the necessity of high resolution models. Here, a selection of simulation models of the human skin and of the eye as well as of the excitation field are presented together with a proposal to assess the appropriate dielectric tissue parameters.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132737579","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 how the equivalent dipole model can be constructed from the time domain measurements of the near fields. This equivalent model can then be used to accurately reproduce the emissions from the circuit board in both the near and far field. However, it is found that there are many challenges to such an approach as such a technique will require a large measurement data set to be acquired which may be very time consuming and the solution can be ill conditioned.","PeriodicalId":377100,"journal":{"name":"International Symposium on Electromagnetic Compatibility - EMC EUROPE","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131661484","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 H-field radiation is generated by considering an ultra-short excitation current. The proposed method is based on the combination of the Fourier and plane wave spectrum (PWS) transforms associated with the Maxwell-Ampere relation. The relevance of the method was confirmed by considering a set of dipoles placed arbitrarily in the horizontal plane and excited by a pulse current of 0.6 ns width at half-height. Magnetic field components Hx, y(t) were calculated in the rectangular plane above the dipoles at different heights in the near-field range.
