The field intensity and directive gains in the normal direction to a corner aperture and radiation resistances of the dipoles with different lengths were calculated depending on a spacing S, type and magnitude of dipole surface impedance.

We develop a quadrature for the numerical integration over a finite domain [a, b]. In domain [a, b], the integrand function is appropriately interpolated using Prony’s method, taking into account the optimal estimation of the complex exponents existing in the interpolation formula. This optimal selection is chosen by examining the principal value of the involved logarithm, and allows for improved convergence. The convergence and accuracy of the MPI method is demonstrated by comparisons with the alternative Gauss-Kronrod quadrature, which is suitable for integrating highly oscillating functions. Different numerical results are presented.

Studies show that cancer cells accept and accumulate NP more preferable than normal cells [1]. We have shown in [1], that heat production mechanism for Dartmouth mNP cannot be hysteresis. In this paper, we present experimental SAR measurement for Dartmouth mNP and give simulation results taking in account viscous friction loss as the main mechanism of SAR production. We have modeled eddy current heat generation in phantom as well as in the realistic human model. Results show that the eddy current heat effect is the same order as in mNP, which exhibits necessity of mechanism for eddy currents minimization.","PeriodicalId":146873,"journal":{"name":"2018 XXIIIrd International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134646318","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}
