An investigation on plasma antennas
Tiğrek, Recep Fırat; Hızal, Altunkan; Department of Electrical and Electronics Engineering (2005)
The plasma antennas offer a new solution to new requirements that are imposed on antenna systems with the advancing communication technology and increasing demand on wider frequency bands. In this thesis the plasma antennas are investigated for the radar and communication applications. The interaction of gas and semiconductor plasma with electromagnetic waves is inspected theoretically, and several experiments on the interaction of microwaves with gas plasma are conducted. Results of these experiments show ...
Investigation of plasma deposited hexagonal boron nitride thin films
Anutgan, Mustafa; Katırcıoğlu, Bayram; Department of Physics (2007)
Hexagonal boron nitride (h-BN) thin films are deposited by plasma enhanced chemical vapor deposition (PECVD). Effects of heat treatment and source gases on the structure and physical properties are investigated. Chemical bonding is analyzed in comparison with the better understood isoelectronic carbon compound, graphite. It seems that the basic difference between h-BN and graphite arises from the different electronegativities of boron and nitrogen atoms. Optical absorptions in UV-visible range for crystalli...
Thermodynamic analysis of plasma-assisted reforming of methane
Maşera, Kemal; Taylan, Onur; Sustainable Environment and Energy Systems (2016-6)
Conventional techniques of syngas production use the exhaust gas of combustion of fossil fuels or feedstock like biomass itself. High temperatures are required for this process. To achieve necessary high temperatures, about 30% of feedstock is used initially. Another disadvantage of these conventional techniques is the tar formation which can damage the system by blocking the equipment. On the other hand, plasma processes are more efficient techniques to convert energy like solar, electrical, etc. int...
Dynamic ion behavior in plasma source ion implantation
Bozkurt, Bilge; Bilikmen, Kadri Sinan; Department of Physics (2006)
The aim of this work is to analytically treat the dynamic ion behavior during the evolution of the ion matrix sheath, considering the industrial application plasma source ion implantation for both planar and cylindrical targets, and then to de-velop a code that simulates this dynamic ion behavior numerically. If the sepa-ration between the electrodes in a discharge tube is small, upon the application of a large potential between the electrodes, an ion matrix sheath is formed, which fills the whole inter-ele...
Improving flow structure and natural convection within fin spacings of plate fin heat sinks
Özet, Mehmet Erdem; Tarı, İlker; Department of Mechanical Engineering (2015)
The main objectives of this thesis are to numerically investigate the previously observed recirculation zones and longitudinal vortices that occur in low fin height plate finned horizontal heat sinks and to improve the flow structures and heat transfer in these zones using various approaches with the help of simulations performed using commercially available CFD software. The approaches used for improvements are replacing the outer most fins with higher ones, introducing gaps on the length of the fins in va...
