The first method is an optimized version of the well known Time Reversal approach, which preserves the method's original simplicity and effectiveness. The second one pursues the focusing task in highly controlled way, by exploiting the convexity of the problem with respect to part of the unknowns (the array's excitations). In particular, it takes advantage of a constrained optimization framework, by imposing proper bounds on the power deposition in healthy tissues.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"114 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87650629","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 antenna is designed on a low cost FR4 substrate and has good performance in terms of gain and efficiency. This property has been achieved by applying a new type of slot-loop resonators in the design. The proposed antenna is designed to operate at 21-23.5 GHz and has consistent performance for different values of dielectric constants and loss tangents. It has high-gain, high-efficiency radiation beams at both sides of the substrate and could be used for mobile base stations (MBS). The proposed planar array could be integrated with the transceivers on the low-cost printed circuit boards (PCBs) to reduce the manufacturing cost.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"10 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88113899","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}

Starting from the zero scattered field condition, a proper manipulation is performed and two different equations are derived: the Contrast-Field-Green Cloaking Equation (CFGCE) and the Contrast Cloaking Equation (CCE). In the present paper, the CCE is deeply analyzed and compared with the existing cloaking approaches in literature. It is shown how Transformation Optics and Scattering Cancellation methods corresponds to the Strong and Weak solutions of the CCE, respectively. This unique equation turns out to be independent from the involved physical events, if the main contrast parameter is properly chosen. Under its main assumptions, the CCE predicts a cloaking effect for arbitrary backgrounds, arbitrary shape objects and arbitrary physics of fields (e.g., magnetic, thermal, acoustic, etc.).","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"28 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86385364","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}

Recently, much progress has been made with numerical integration methods for the evaluation of the singular and near-singular surface integrals occurring in the MoM, especially in the context of using curved surface elements (curvilinear) with higher-order basis functions. The focus here is on the near-singular scalar Green's function kernel, when integrated over a triangle domain. This is a weak near-singularity. A first version of a new near-singularity cancellation quadrature rule is presented, which is constructed by applying a single near-singularity cancellation transformation to the whole domain, without splitting it into three sub-triangle domains as is typically done in other methods. The aim is to reduce the number of required quadrature points for a given accuracy. Promising preliminary results are shown, but there are various aspects that require further investigation and optimization.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"142 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86528067","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 Theory of Characteristic Modes (TCM) has been applied to get physical insight on the radiating behavior of the modes present on a U-slot etched on a finite metallic plate. Different types of U-slot planar structures are presented in order to demonstrate the effects produced by the inclusion of a U-slot in a broadband finite structure. The interaction between the corresponding U-slot modes and the metallic plate modes is fully discussed and justified for two specific cases. The information yielded by the modal analysis reveals the close influence of the plate size on the resonance frequency of the U-slot aperture. On the other hand, the length of the U-slot arms directly affects the resonance frequency of the modes associated to the metallic plate.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"85 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83921596","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}

An improved satellite-to-aircraft channel model will allow more accurate predictions of the reception situation by considering all propagation related effects. This accuracy is important when developing and testing novel systems for critical safety-of-life application. The improvement of the channel model necessitates to assess, among other influences, the effects of the airborne platform on the electromagnetic pattern of the antennae for both fixed- and rotary-winged aircraft and the quantification of the ground-reflection characteristics in the frequency-band of interest.

Subsequently, we use this degree of freedom to exclusively excite the highest-order fast lateral mode, guaranteeing optimal aperture illumination efficiency for arbitrarily-large apertures, without incurring edge-taper losses. We verify our semianalytical calculations with full-wave simulations, showing that the proposed antenna can outperform our previously-introduced cavity-excited Huygens' metasurface antenna, offering a simple and efficient design for compact high-gain antennas.","PeriodicalId":6509,"journal":{"name":"2016 10th European Conference on Antennas and Propagation (EuCAP)","volume":"12 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88966596","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}
