To achieve an optimal operating condition, a good characterization of the lamp in terms of radio frequency equivalent circuits under operating conditions is necessary, enabling the design of an efficient matching network. This paper presents the characterization technique for such lamps and presents the design of the required matching network. For the characterization, a high-intensity discharge lamp was driven by a monofrequent large signal at 2.45 GHz, whereas a frequency sweep over 300 MHz was performed across this signal to measure so-called small-signal hot S-parameters using a vector network analyzer. These parameters are then used as an equivalent load in a circuit simulator to design an appropriate matching network. Using the measured data as a black-box model in the simulation results in a quick and efficient method to simulate and design efficient matching networks in spite of the complex plasma behavior. Furthermore, photometric analysis of high-intensity discharge lamps are carried out, comparing microwave operation to conventional operation.}, language = {en} } @article{SelmerKimDarleyetal.2006, author = {Selmer, Thorsten and Kim, Jihoe and Darley, Daniel and Buckel, Wolfgang}, title = {Characterization of (R)-2-hydroxyisocaproate dehydrogenase and a family III coenzyme A transferase involved in reduction of L-leucine to isocaproate by Clostridium difficile / Kim, J. ; Darley, D. ; Selmer, T. ; Buckel, W.}, series = {Applied and Environmental Microbiology. 72 (2006), H. 9}, journal = {Applied and Environmental Microbiology. 72 (2006), H. 9}, isbn = {0099-2240}, pages = {6062 -- 6069}, year = {2006}, language = {en} } @article{JossekBongaertsSprenger2001, author = {Jossek, Ralf and Bongaerts, Johannes and Sprenger, Georg A.}, title = {Characterization of a new feedback-resistant 3-deoxy-D-arabinoheptulosonate 7-phosphate synthase AroF of Escherichia coli}, series = {FEMS microbiology letters}, volume = {Vol. 202}, journal = {FEMS microbiology letters}, number = {Iss. 1}, issn = {1574-6968}, pages = {145 -- 148}, year = {2001}, language = {en} } @article{SchusserPoghossianBaeckeretal.2012, author = {Schusser, Sebastian and Poghossian, Arshak and B{\"a}cker, Matthias and Leinhos, Marcel and Wagner, Patrick and Sch{\"o}ning, Michael Josef}, title = {Characterization of biodegradable polymers with capacitive field-effect sensors}, series = {Sensors and actuators B: Chemical}, volume = {187}, journal = {Sensors and actuators B: Chemical}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0925-4005}, doi = {10.1016/j.snb.2012.07.099}, pages = {2 -- 7}, year = {2012}, abstract = {In vitro studies of the degradation kinetic of biopolymers are essential for the design and optimization of implantable biomedical devices. In the presented work, a field-effect capacitive sensor has been applied for the real-time and in situ monitoring of degradation processes of biopolymers for the first time. The polymer-covered field-effect sensor is, in principle, capable to detect any changes in bulk, surface and interface properties of the polymer induced by degradation processes. The feasibility of this approach has been experimentally proven by using the commercially available biomedical polymer poly(D,L-lactic acid) (PDLLA) as a model system. PDLLA films of different thicknesses were deposited on the Ta₂O₅-gate surface of the field-effect structure from a polymer solution by means of spin-coating method. The polymer-modified field-effect sensors have been characterized by means of capacitance-voltage and impedance-spectroscopy method. The degradation of the PDLLA was accelerated by changing the degradation medium from neutral (pH 7.2) to alkaline (pH 9) condition, resulting in drastic changes in the capacitance and impedance spectra of the polymer-modified field-effect sensor.}, language = {en} } @article{MukherjeeRamazaniYangetal.2011, author = {Mukherjee, Krishnendu and Ramazani, Ali and Yang, Li and Prahl, Ulrich and Bleck, Wolfgang and Reisgen, Uwe and Schleser, Markus and Abdurakhmanov, Aydemir}, title = {Characterization of gas metal arc welded hot rolled DP600 steel}, series = {Steel research international}, volume = {Vol. 82}, journal = {Steel research international}, number = {Iss. 12}, publisher = {Wiley}, address = {Weinheim}, issn = {1869-344X (E-Book); 1611-3683 (Print)}, pages = {1408 -- 1416}, year = {2011}, language = {en} } @article{FoersterMorvicBetkoetal.1999, author = {F{\"o}rster, Arnold and Morvic, M. and Betko, J. and Novak, J.}, title = {Characterization of low-temperature GaAs by conductivity, Hall effect and magnetoresistance measurements.
