We study only the case when the disks are placed on the one side of the half-plane. The meshless full-wave code is based on the operator method. The scattered field is expressed in terms of the superposition of the plane waves with the use of the Fourier integrals with unknown amplitudes. The operator equations for these amplitudes are reduced to the integral equations. Since the scattering operators of the half-plane have singularities, the regularization procedure is performed. The scattered field can be represented as a superposition of the plane wave, cylindrical and spherical waves. The far field of the spherical waves and the total near field is studied.","PeriodicalId":297673,"journal":{"name":"2022 IEEE 2nd Ukrainian Microwave Week (UkrMW)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123609027","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}

Visual quality metrics play a key role in this sense, since their use allows determining the need in different image processing operations, their type and parameters, automating the entire process. The paper considers the problem of using no-reference visual quality metrics and test image databases to solve such problems. The effectiveness of more than 40 existing visual quality metrics for images with typical distortions for UAVs has been evaluated. The paper proposes a combined metric based on an artificial neural network to improve the accuracy of visual quality assessment and the possibility of its application in practice with sufficient efficiency.","PeriodicalId":297673,"journal":{"name":"2022 IEEE 2nd Ukrainian Microwave Week (UkrMW)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128260050","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}

To prevent unwanted detuning of array elements, preamplifier decoupling is used. So far, the decoupling circuit design was based on intuitive approach of minimizing impedance presented to the terminals of the loop. The approach leads to decent but not optimal results. In this paper a systematic analytical method is used to derive the exact condition for maximum decoupling of shielded loops in array. The condition describes precisely what impedance should be presented to the terminals of the loop for best decoupling. It is shown that the method is valid for single- and multi-gap shielded loops with and without integrated reactive components across the gap. The presented results are useful in the design of MRI receive arrays of shielded loop coils with optimal decoupling.","PeriodicalId":297673,"journal":{"name":"2022 IEEE 2nd Ukrainian Microwave Week (UkrMW)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117158017","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}
