Radiating element of the antenna is a planar meander line which exhibits multiple narrowband resonances and has been built on FR4 substrate. When the meanderline radiating element is loaded by an additional FR4 layer on top, the resonances shift down in frequency. If the top dielectric is metallized at one end, these resonances shift further down. This effect is enhanced if a metallized bottom dielectric is also employed. And for this case, the resonances eventually merge and form a broadband response.","PeriodicalId":152036,"journal":{"name":"2019 Fifth International Electromagnetic Compatibility Conference (EMC Turkiye)","volume":"2 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114291025","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}

Thus, their accurate numerical calculations are very important in modeling and simulation studies. In this sense, the effect of different-sized non-uniform FDTD meshes on the numerical calculation of the cavity resonances is investigated in this study. Three different non-uniform FDTD meshes are used for accuracy evaluations. A two-dimensional rectangular cavity problem is solved as a numerical example. The calculated resonance frequencies are compared with a uniform mesh result. The accuracy of each mesh type is analyzed in detail.","PeriodicalId":152036,"journal":{"name":"2019 Fifth International Electromagnetic Compatibility Conference (EMC Turkiye)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129722873","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}

NZI properties make it possible to generate beams from planar surfaces, while numerical results show that the behavior of a shell is very sensitive to the geometric parameters and the nature of the NZI, i.e., permittivity and permeability values. We show that, by using asymmetric cavities and pyramidal textures, it is possible to generate asymmetric beams with suitable choices of dimensions and material properties.","PeriodicalId":152036,"journal":{"name":"2019 Fifth International Electromagnetic Compatibility Conference (EMC Turkiye)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129134269","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 array achieves a measured 52% frequency bandwidth for voltage standing-wave ratio<2, 4–5 dBi absolute gain and >14 dB front to back ratio. Back lobes have low levels therefore the total interference which effects to the other package circuits are suppressed.

The performance of the antenna arrays was tested for flexibility and different input powers. A three-layer bone phantom was created, including skin, fat, muscle. The antenna performance was evaluated in terms of return loss and directivity characteristics. Variable input power (1W − 5W) was applied. The specific absorption rate (SAR) was calculated through the electromagnetic simulations and it was used as an input for the thermal simulations. According to the results of the thermal simulations performed on the phantom, temperature rise on tumor tissue (15mm) placed in the bone was examined. The effectiveness of the antenna array, designed for use in the treatment of bone tumors, was examined according to different input powers for 20 min exposure time.","PeriodicalId":152036,"journal":{"name":"2019 Fifth International Electromagnetic Compatibility Conference (EMC Turkiye)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134459432","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}

In an aircraft not only a number of electronic systems operate in a confined space but also the external Electromagnetic Environment (EME) has become very harsh, due to presence of high power transmitters and more significantly lightning associated EM fields. Thus EMC testing of aircraft is a complex and costly undertaking where during testing High Intensity Radiated Fields (HIRF) of magnitudes comparable to actual conditions has to be generated. In recent past an innovative approach has been formulated to make this testing easier to perform, namely Low Level Coupling (LLC) tests. Where transfer functions are computed through simulations that can predict the resultant surface currents and EM fields on & inside the fuselage, which grossly lowers test level magnitudes. Therefore, the testing can be done at much lower levels. However, a calculation of these transfer functions requires intricate 3DEM simulations and is time extensive. So far the transfer functions computed by aviation regulatory authorities are generic in nature. This paper elaborates computation of more specific transfer functions, taking into account the effect of additional factors like apertures and orientation of wires, whereas the original transfer function is dependent on fuselage length only. Results are computed through 3D EM simulations and presented and analyzed.","PeriodicalId":152036,"journal":{"name":"2019 Fifth International Electromagnetic Compatibility Conference (EMC Turkiye)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127514757","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}
