We present the first results for the chemical microscopy of hepatocytes (liver cells) using a frequency of 2920 cm/sup -1/ coinciding with the absorption band of lipids and at 1.5 /spl mu/m corresponding to the overtones of water. Infrared microscopy allows studying processes of living cells in cases where fluorescence markers are cell damaging, alter the natural function of a protein in a cell or where labeling is impossible. In the infrared spectral range, accessible to our laser systems, substances can be identified according to their specific absorption in the so-called fingerprint region. Moreover, the absorption is directly proportional to the number of molecules, which makes it the appropriate method for quantitative measurements. Our method opens the possibility to investigate rapid changes of chemical behavior and the dynamics of small bio-molecules in living cells. In addition, we demonstrate by using near-field microscopy a spatial resolution of less than 30 nm (/spl Lt//spl lambda//100) at /spl lambda/=3222 nm (3104 cm/sup -1/).","PeriodicalId":13627,"journal":{"name":"Infrared and Millimeter Waves, Conference Digest of the 2004 Joint 29th International Conference on 2004 and 12th International Conference on Terahertz Electronics, 2004.","volume":"71 1","pages":"777-778"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81626685","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}

We observed that the transmission peak frequency changes drastically with increasing the thickness of the dielectric layer which is attached to the metal surface.

In addition, we measured transmission spectra of the metal hole array, the diameter of which is much smaller than the wavelength of the THz wave. By optimizing the surface structure of the metal hole array for the excitation of the surface plasmon-polaritons, the strong enhancement of the transmission of the terahertz wave was obtained.","PeriodicalId":13627,"journal":{"name":"Infrared and Millimeter Waves, Conference Digest of the 2004 Joint 29th International Conference on 2004 and 12th International Conference on Terahertz Electronics, 2004.","volume":"1 1","pages":"137-138"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79779544","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}

Design, device fabrication, most of the mixer hardware fabrication, space-qualification, and final assembly are all realized at KOSMA. Thanks to the modular design RF- and IF-performance of different parts of the MU are tested separately before final assembly. Latest test results show a noise temperature between 80 K in the band centre towards 220 K at the upper band edge at 2.8 K operating temperature. The mixer IF-ripple is below 2 dB over a 4-8 GHz bandwidth including the bias-T which provides a very high EMI and ESD protection. The mixer performance and design are discussed under the aspect of the careful trade off between performance, reliability, timely delivery, and resources.","PeriodicalId":13627,"journal":{"name":"Infrared and Millimeter Waves, Conference Digest of the 2004 Joint 29th International Conference on 2004 and 12th International Conference on Terahertz Electronics, 2004.","volume":"4 1","pages":"437-438"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85111999","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}
