Both triangular - and rectangular SIW cavities are combined for the first time in the design of band pass filter. Cross-coupling structures are realized in both proposed filters via two or three propagation paths. Measured results are presented and compared to those simulated by Ansoft's High Frequency Structure Simulator (HFSS) software package. A good agreement between the simulated and measured results is observed, which has also validated the proposed filtering structure with hybrid-shaped SIW cavities.","PeriodicalId":319991,"journal":{"name":"2015 IEEE International Conference on Communication Problem-Solving (ICCP)","volume":"9 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123659006","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 idea of Short-time Fourier transform (STFT) is physically realized in our scheme. The Fourier processor based upon a four-wave mixing time lens is used to perform the process of Fourier transformation. The ultra-short optical input signal is divided to multiple duplicates that is delayed in turn, and different short period of time of multiple duplicates are separately transformed into the frequency domain by multiple time lens. Pump pulse is both worked as the provider who has the quadratic phase and the window function of STFT. Simulations have been done to investigate performance of the time-frequency scheme compared with STFT using FFT algorithm.","PeriodicalId":319991,"journal":{"name":"2015 IEEE International Conference on Communication Problem-Solving (ICCP)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124804302","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}
