They have already leaded to many unprecedented microwave applications, which may be classified in three categories: guided-wave, radiated-wave and refracted-wave applications. Control and manipulation of electromagnetic waves is at the heart of many industries from wireless communication, Internet and optical data storage to imaging and displays. Progress in these technologies places challenging demands on material properties and therefore structured electromagnetic materials. Metamaterials are a special class of structured materials. In this paper, harmonics resonance frequency of embedded CRLH-TL array has been generated and introduced. The analysis and investigation are done by a commercial software. The good agreement between the theoretical expectation and the simulation results is observed. Finally, the application of the proposed CRLH-TL array was examined in microstrip antenna design. The proposed microstrip antenna structure has been fabricated and the measured S-parameters of the proposed structure can be analyzed with network analyzer to demonstrate the excellent performance and satisfy multiband frequencies using conventional single microstrip patch antenna.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125133168","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}

However no such array has been made to date. The reason for this lies in the complexity of building the key component of this SPA - the super lens. Here, we shall demonstrate how this complexity can be greatly reduced by constructing the simplest possible compact super lens. The method used is generic and can be adapted to create a SPA of any arbitrary geometry. This simplification will lead towards the possibility of constructing a practical SPA.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126137501","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}

For the general asymmetric case, where the line is loaded with different CSRRs at each stage (pair), the structure exhibits negative effective permittivity in the vicinity of two different frequencies, i.e., it behaves as a dual-band epsilon-negative (ENG) transmission line metamaterial. A lumped element equivalent circuit model of the unit cell of these artificial lines, that includes the electric coupling between the CSRRs forming the pair, is proposed. This model is analyzed in detail and the equation that provides the transmission zero frequencies is derived. Finally, the model is validated by comparing electromagnetic simulation and experimental data to circuit simulations with extracted parameters. These structures may be applied to the design of stop band filters, including dual-band notched filters, and sensors based on frequency splitting.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"515 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132719656","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 availability of a rigorous model allows us demonstrating that the use of nanoparticles with high eccentricity is able to generate a scattering cancellation effect within the entire optical range, strongly relaxing the current requirements on the nanoparticles size.

As the structures are in the ~100 nm length scale are based on metals, plasmonic color printing enables high resolution and fade-free prints.
