The total field is sought in terms of vector modal solutions of the source-free Maxwell equations. The content of the modal spectrum is determined and the eigenmodes of the homogeneous magnetoplasma are found to form a continuous set. The source-excited field is represented by an integral expansion in terms of the obtained continuous-spectrum modes and the expansion coefficients of such a field representation are derived in explicit form using the mode orthogonality relation. The developed approach is applied to the analysis of radiation from a rotating magnetic-field source in the whistler frequency range.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"19 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":"131361405","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}

A large variety of electromagnetic (EM) modelling tools has been developed and is available as both commercial software suites and highly specialized scientific codes that are able to handle extremely complex tasks of EM simulation. With the growing relevance of automotive radar and 5G systems during the last few years, CEM methods have gained an even higher level of significance. As an example, automotive radars for autonomous driving are sometimes required to be tested over more than one million kilometers, which in many cases is hardly feasible in real experiments. In the context of military aircraft, ships, or other vehicles, the radar cross section (RCS) is a crucial figure, which, during the planning stage, can be obtained only in simulations.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"201 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":"132132282","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}

Several experimental campaigns both on in-vivo and ex-vivo tissues were proposed worldwide, characterising the dielectric properties of biological tissues from about few hundred MHz up to 50 GHz; however, the reported data from different studies do not always converge even when they refer to the same type of tissue or organ. The reasons for this uncertainty could be several; in particular, special attention has to be done to follow a strict measurement protocol, allowing for minimal sample preparation and thus minimal dehydration of sample. This is because at the frequency of interest the polarisation is mainly attributed to the ‘water’ content in the sample under test. Thus, in this paper we propose the use hydration as a possible classifier for accurately processing the measured dielectric properties of kidney samples.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"318 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":"131575901","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 this paper, a low-loss transmitarray antenna (TAA) fed by a $6times 6$ phased array antenna (PAA) for high-gain conical beam scanning is proposed at 60 GHz. The TAA element is with the arrow-shaped metallic pattern in the middle layer and two polarizers in the upper and bottom layers. The PAA feed element is the printed patch antenna with equivalent metallic cavity, showing an advantage of ease of integration with the control circuits. Simulated results show that the proposed PAA-fed TAA features a peak simulated gain of 29.89 dBi in the broadside direction, corresponding to the aperture efficiency of 53.9%, together with a narrow conical beam scanning with a ∼2 dB beam crossover.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","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":"131038289","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 receiving antenna response to these waves can be quite complicated, and its effective length can differ significantly from the antenna geometric length. We analyze how the effective length depends on the parameters of the incident quasi-electrostatic waves. We study its dependence (a) on the distance between the wave source and the receiving antenna, (b) on the spatial scales of the incident wave electric field, and (c) on the frequency of the quasi-electrostatic waves. In particular, we show that dependence of the effective length on the wave frequency has multiple resonances, and their frequencies depend only weakly on the the antenna orientation and geometry. We apply the results to the satellite observations of the oblique whistler-mode chorus emissions propagating in the Earth's magnetosphere.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"4 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":"133457168","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}

Quality (Q) factor is the most important characteristic of the resonator showing its ability to amplify the external electromagnetic field. There are a lot of types of optical resonator, e.g., photonic crystal cavities, Fabry-Perot resonators, whispering gallery mode resonator and many others. The high record values of Q factor today rich giant values up 1010. However, decrease of the size of any named above resonators results in exponential drop of their Q factor. When the size of the resonator is comparable with vacuum wavelength (the case of the lower Mie-resonance), the value of Q-factors is about 10-20, which is not enough for many practical applications. Therefore, the quest for compact photonic systems makes a new query for small high-Q resonators, using fundamentally new principles of light trapping.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"24 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":"132171446","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}
