The normalised phase coefficient, ß/k0, is calculated for a range of values for the two media, first with (¿r1 = 1, ¿r1 = 1) and then with (¿r1 = 1, ¿r1 = -1) assuming - 5 < ¿r2/¿r1 < 5, -5 ¿r2/¿r1 < 0. This range of parameters includes some \"double negative\" cases for the second medium. Dispersion diagrams are presented for the case where region 1 is an artificial magnetic dielectric and region 2 is a semiconductor plasma. The results have implications for the design of miniature passive components.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129664683","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}

Existing designs of sand monitor are widely used and often provide useful results, but they can require regular calibration and may struggle to provide reliable quantitative measurements.

Experimental results of various mixtures including sand will be presented.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132063916","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 new design approach utilizes switching operation of FETs. All input power, in this configuration, is directed alternately to each single branch of a pair of parallelly connected FETs corresponding with the polarity of the anti-phase input signal without split of the input power, thereby resulting in enhancing conversion gain. Measurement results demonstrate improvement of 2.87 dB in conversion gain and output power relative to a single-ended structure. For doubling from 5 to 10 GHz the new scheme shows a maximum conversion gain of 11.67 dB.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131939590","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 antenna set up is a bi-static one with two Archimedean spirals with opposite sense of rotation. A particular property of the radar is that it transmits and receives a set of eight frequencies at the same time. The system parameters are particularly aimed at imaging algorithms exploiting the phase evolution over the antenna footprint.

These techniques are the bi-orthonormal-basis combined with the orthonormal-basis method, the hybrid mode-matching/spectral method, and, finally, the BI-RME (Boundary Integral-Resonant Mode Expansion) method. Then, two prototypes of band-pass filters have been designed in this work using a CAD tool developed in the research groups implicated in this manuscript. The procedure described in this paper only involves a limited number of actual physical parameters at each step so that it is computationally very efficient and rapidly convergent. Improving the performance of the standard all-inductive filters (without dielectric resonators), the novel topologies present a reduction of the volume and a larger band free of spurious, maintaining the low-cost high-precision manufacturing properties.","PeriodicalId":156210,"journal":{"name":"2003 33rd European Microwave Conference, 2003","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121999498","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}
