As the system responses matrix is related to the array geometry, the topology of a MIMO array has a huge impact in CS reconstruction. Numerical simulations demonstrate that the curvilinear array achieves better reconstruction than the Mills Cross array and uniform rectilinear array. Moreover, the traditional point spread function (PSF) is more suitable than the CS PSF for evaluating the performance of a CS imaging system.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"2007 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":"123772344","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 well-known objet having the same geometry and homogeneous material properties is exploited as a reference. Hence only small variations from reference configuration are of interest. Starting from the Volumetric-Perturbative Reciprocal Theory (VPRT), we derive an expression of the relationship between the reference configuration (which is supposed perfectly known) and the perturbed one: in addition to the permittivity, we extend the VPRT to permeability perturbations and we derive the first and second order expression. In the case of axisymmetric objects having axisymmetric perturbations, we derive a particular expression reducing the volume integral into surface one. The resulting formulation can be used in a direct way, for example to propagate uncertainties, as well as to solve an inverse problem for example in non-destructive testing applications.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"31 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":"121846178","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 operation principle is based on a Distributed Reactive Nearfield Parasitic Element (DRNPE). The DRNPE unit cell with high distributed inductive reactance is introduced near a highly capacitive open ended CPW transmission line, provides a high impedance matching. The resonant frequency is independent of the transmission line parameters and hence can be tuned with respect to the DRNPE parameters. The prototype used as a sensor for the measurement of dielectric constant variation is also discussed. The simulation is carried out using Ansoft HFSS and measurement using HP8510C Vector Network Analyzer.","PeriodicalId":112989,"journal":{"name":"2018 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"22 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":"132924636","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}
