It uses a wave guide, operated below his cut off frequency to eliminate the far field of the antenna. Using two measurements (with and without Wheeler Cap) it is possible to calculate the radiation efficiency. In this paper the impact of different shapes, material and the minimum heights of the Wheeler Cap are investigated. The measurement of radiation efficiency is not precise but the ease of measurement makes the method highly attractive. This contribution concludes that the shape and the material have no influence to the measured radiation efficiency as long as the design criterion like cap size are kept constant.","PeriodicalId":261643,"journal":{"name":"2011 International Students and Young Scientists Workshop \"Photonics and Microsystems\"","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122526108","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}

Thin films were performed by high energy reactive magnetron sputtering process. During deposition, particles were sputtered from metallic Ti and Ti-Tb targets in oxygen reactive plasma. The properties of thin films were characterized by several methods. Influence of Tb-dopant on the structure and diversification of the surface was investigated by X-ray Diffraction and Atomic Force Microscopy, respectively. Optical properties of manufactured films, especially transparency level and adsorption edge, were determined based on optical transmission measurements. Photocatalytic activity of TiO2:Tb thin films was determined based on phenol decomposition reactions under UV-Vis light exposure. The rate of phenol decomposition was determined based on absorption measurements. The results have shown that all manufactured films were nanocrystalline and photocatalytically active. Doping with terbium meaningfully increased the activity of as-deposited films. In this paper dependences between structure type of the TiO2-matrix, crystallites size, roughness of the thin film surface and photocatalytic activity of TiO2:Tb thin films are described. Especially, the key-role of terbium on properties of TiO2 matrix is discussed.","PeriodicalId":261643,"journal":{"name":"2011 International Students and Young Scientists Workshop \"Photonics and Microsystems\"","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116441119","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 crucial part of these links is the broadband optical receiver transforming the signal from high optical to millimeter-wave frequencies at each base station. A new integrated optical receiver chip with an integrated antenna structure supporting more than 100GHz bandwidth is available. To be compatible to standard millimeter-wave components based on hollow metal waveguide structures an efficient coupling solution from the chip to waveguide has to be designed. For the performance of this element the impedance matching to the integrated photo diode is the dominating task. Therefore models of the chip structure with different complexity and computational effort were created and numerically simulated using the Method of Moments and compared with analytical models and empirical results. Since the computational effort of the whole structure is high, it is of interest to what detail the structure has to be modeled for an efficient design process of a coupling solution to a hollow metal waveguide. Radiation patterns of the models are investigated in order to determine a suitable coupling direction.","PeriodicalId":261643,"journal":{"name":"2011 International Students and Young Scientists Workshop \"Photonics and Microsystems\"","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133658530","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}
