A dielectric perturber is attached to the end of a PET cantilever beam and suspended above the designed DBBPF. By applying a DC bias voltage, the PET actuator vertically lifts up or pulls down the attached dielectric perturber. The height of the dielectric perturber from the DBBPF determines the effective dielectric constant, causing a variation of the filter's center frequency. The proposed DBBPF provides concurrent dual passband tuning operation for multiband wireless systems.","PeriodicalId":334390,"journal":{"name":"2017 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122152241","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}

FSSs are two-dimensional periodic structures that behave like either passband or stop band filters in the microwave frequency band. SRRs are artificially created structures with nonmagnetic loops and small gaps between them. Using COMSOL Multi-physics, we investigate the transmission characteristics of such structures with variation of the physical parameters gap width, dielectric constant, gap separation, and incident angle. This analysis offers a new approach in the design of metamaterial based radio frequency(RF) devices.","PeriodicalId":334390,"journal":{"name":"2017 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132112112","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 question was given a positive answer in a recent internship after which a prototype for (de-)compression was tested in two field experiments. Large volumes of weather were shown to be reduced to less than a percent of the original datasets but this came with the price of information loss. In this study a method for lossy compression of weather data is described by representing the data as a sparse and adaptive subset. Adaptive sampling is then solving an optimization problem for the minimal loss of information for applications in radar propagation modeling.","PeriodicalId":334390,"journal":{"name":"2017 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122158322","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}

Micromixer-based gain-enhanced technique, i.e. inductive series-peaking gain-enhanced single-in differential-out (SIDO) class-AB RF GM stage, is used to increase the output impedance and suppress the feedback capacitance Cgd of RF GM stage. Hence, conversion gain (CG), noise figure (NF) and LO-RF isolation of the mixer can be enhanced. The mixer consumes 7.2 mW and achieves excellent RF-port input reflection coefficient of −10∼ −14.4 dB for frequencies of 81.4∼110 GHz. The corresponding −10 dB input matching bandwidth is greater than 28.6 GHz. In addition, for frequencies of 90∼96 GHz, the mixer achieves CG of 10.5∼12 dB (the corresponding 3-dB CG bandwidth is 22 GHz) and LO-RF isolation of 40.2∼46.2 dB, one of the best CG and LO-RF isolation results ever reported for a down-conversion mixer with operation frequency around 94 GHz. Furthermore, the mixer achieves an input third-order intercept point (IIP3) of 1 dBm at 94 GHz. These results demonstrate the proposed down-conversion mixer architecture is very promising for 94 GHz image radar sensors.","PeriodicalId":334390,"journal":{"name":"2017 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125728504","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}
