The filter is based on fourth order coupling of coupled gap composite right left handed transmission line resonators. The resonators are designed to demonstrate a zeroth order mode at the passband center frequency for filter size reduction. The filter has a compact size 20×20 mm2. The design concepts of the coupled filter response are discussed and verified using full electromagnetic full wave simulations and confirmed by experimental measurements with good agreements. The results confirm that the filter has 1.5 dB insertion loss and better than -25 transmission zero.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"6 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":"129518367","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 required conditions for eliminating reflections (no back-scattered power) and shadow (no change in the field strength behind the screen) as well for full tunneling of energy are investigated. It is shown that positioning an active layer behind a highly reflective metallic sheet, one can fully recreate the incident wave behind the shield. Finally we show that a parity-time-symmetric pair of a lossy layer in front and an active layer behind the metallic layer makes both forward and backward scattered powers zero.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"32 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":"133097428","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}

This kind of filter utilizes the possibility of independent tuning of two types of resonances that occur in ENZ waveguides using short slot cuts in the ENZ channels. By forming a dual-channel configuration, a second-order bandpass filter can be obtained using zero-order-resonance (ZOR) from one channel and Fabry-Perot (FP) resonance from the other one (whose frequency is slightly different from ZOR). Both resonances can be simultaneously and equally tuned by changing the respective slots' lengths. The maximum observed passband shift is 900 MHz or 8.3%. During filter tuning, 3 dB-bandwidth varies between 330 MHz (3.4%) and 470 MHz (4.4%) as the length of the tuning slots decreases. Maximum insertion loss observed is 1.8 dB.","PeriodicalId":143626,"journal":{"name":"2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":"14 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":"115095662","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 presentation gives the results of depolarization coefficient calculation from reflection and transmission spectra of simulated in finite difference time domain method test structures and from experimentally measured spectra of samples with non-uniform nanoparticles distribution.
