The method is characterized by very low numerical dispersion errors. Furthermore, it is explicit by construction and easily parallelizable. It provides a much better alternative for particle based simulations compared to the conventional FDTD method. In particular, in the context of the emerging PWFA technology this approach may lead to a substantial reduction of simulation times.","PeriodicalId":375707,"journal":{"name":"2010 International Conference on Electromagnetics in Advanced Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130156383","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 conventional narrow BPF with λg/2 open stubs is first designed using series λg/2 open stubs and λg/4 transmission lines. Then, a DB filter can then be easily implemented by replacing the microstrip lines with the CRLH transmission line unit-cells. The DB BPF using the CRLH transmission line unit-cell is experimentally demonstrated at dual operating frequencies of 5.8 GHz and 10.02 GHz. The experimental results are in a good agreement with the simulation results. The DB BPF shows 11 % and 13 % pass bandwidth at the center frequencies of 5.8 GHz and 10.02 GHz, respectively.","PeriodicalId":375707,"journal":{"name":"2010 International Conference on Electromagnetics in Advanced Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130768820","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 delay line using similar periodic structures of right-handed waveguide is also developed for grating lobe suppression of slot array antennas with travelling-wave excitation. The left-handed waveguide is composed of periodic structures as the pair of an inductive iris for shunt inductance and a short stub for series capacitance. The delay line of the right-handed waveguide is composed of a capacitive iris for shunt capacitance and a shorter short stub for series inductance. Dispersion diagram is estimated by Bloch analysis in the design. Left-handed phenomenon with phase variation of mechanically-controlled phase shifter and shortening wavelength due to the delay line are confirmed in the experiments.","PeriodicalId":375707,"journal":{"name":"2010 International Conference on Electromagnetics in Advanced Applications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127846463","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}
