The performance of memory polynomial model in fixed point implementation degrades, and LSP model has been proposed as a solution. The performance is evaluated in terms of simulation and measured result. It has been reported that we achieve numerically stable observation matrices using splines, hence accuracy level of coefficients is sufficient to cover full dynamic range in FPGA.","PeriodicalId":166478,"journal":{"name":"2016 Asia-Pacific Microwave Conference (APMC)","volume":"355 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122801241","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 dual band filter consists of a dual split ring resonator having splits on opposite sides with inductive short stub split ring resonator (ISSSRR). Even and odd mode analysis has been performed to calculate the resonance frequencies. Three transmission zeros(TZs) are achieved between two passbands by both electric or magnetic dominant coupling and also cancellation effect of electric and magnetic coupling, resulting in high passband selectivity and improved band-to-band isolation. The proposed dual band pass filter has the advantages of being compact with more degree of freedom to achieve desired pass bands by controlling the electric and magnetic coupling.

The proposed generator is constructed by a group of transformation cylinders filled with metamaterials. Using transformation cylinders, arbitrary-way planar wave fronts can be simultaneously converted to helical wave fronts with arbitrary topological charges. Firstly, the principle of orbital angular momentum is introduced. Then, a designing method of metamaterials based on transformation optics is interpreted to construct a 3D simultaneous arbitrary-way OAM generator with different topological charges. At last, the simulations on electric field and phase of output beams are performed, which validate the function of this design. The results show that arbitrary-way beams carrying OAM with specific topological charges can be obtained simultaneous by the proposed device.","PeriodicalId":166478,"journal":{"name":"2016 Asia-Pacific Microwave Conference (APMC)","volume":"354 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115926919","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}

ERA gives high gain due to presence of multiple reflections between completely reflecting ground plane surface and partially reflecting dielectric surface. Non-uniform phase distribution of electric field over the ERA aperture generally degrades the radiation characteristics of antenna. In order to achieve further gain improvement, planar multi-dielectric PCS is used to transform non-uniform phase distribution to relatively uniform phase distribution over the ERA aperture.","PeriodicalId":166478,"journal":{"name":"2016 Asia-Pacific Microwave Conference (APMC)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121726142","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}
