Design and construction of a microwave cavity for oil-water emulsion separationKunzi, Tekweme 04 June 2012 (has links)
M. Tech. / The mechanism of microwave assisted waste oil and water emulsions destabilisation is analysed. The broad overall features of the microwave system to break emulsions are established and the design specifications of each constituent component are set. The type of well suited microwave cavity is selected. After analysis, the multimode cavity proves to be a suitable choice. The established overall dimensions of the cavity are set and used to visualize the field pattern in the treatment chamber. Some MATLAB routines are written and used to enhance the visualization of the field pattern inside the microwave cavity. The individual excited modes are first visualised, followed by the resultant electric field. The detailed descriptions of the drawing are then finalised and the microwave system constituents selected. The cavity is manufactured and tested for leakage. The test shows that the cavity is watertight.

The design and implementation of microwave receiver front end componentsNetshifhire, Vhudilangi Patrick 12 1900 (has links)
Thesis (MScEng)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: Different types of RF and Microwave receiver systems architectures are investigated. The
superheterodyne receiver characteristics are studied qualitatively. A three components system
(LNA, Mixer and VeO) is selected and the components are first measured individually, and then
measured as a single system. A mono filar axial mode helix antenna is designed, simulated using
FEKO and constructed. A narrow band interdigital bandpass filter is designed using the
capacitance network and its transformation, and it is simulated using two different simulation
packages, eST Microwave Studio and AWR Microwave Office. Two filter prototypes are
fabricated using cylindrical rods. An open circuited microstrip resonator oscillator is designed
and implemented through the negative resistance method. Its performance is verified using the
harmonic balance simulator in AWR MWO. A single balanced mixer is designed and
implemented using 1800 hybrid junction (rat-race) and it is also fabricated using microstrip
transmission line technology. All designed components performed well in comparison to their
predicted performance. The LNA and three of the designed components (Filter, Oscillator and a
Mixer) are connected together and characterized as a single four block system. The system
performed well except for the IF signal which shift to a lower frequency due to oscillator load pulling. / AFRIKAANSE OPSOMMING: Die argitektuur van verskeie RF en Mikrogolf ontvanger stelsels word ondersoek. Die
"superheterodyne" ontvanger eienskappe is kwalitatief bestudeer. 'n Stelsel wat uit drie
komponente bestaan (LNA, Menger en VeO) is bestudeer. Die individuele komponente is eers
gemeet en daarna die stelsel as 'n eenheid. 'n "Mono filar" aksiale modus heliks antenna is
ontwerp, gesimuleer met FEKO en gebou. Verder is 'n nouband inter-digitale banddeurlaat filter
ontwerp met behulp van die kapasitiewe network metode en sy transformasie. Hierdie ontwerp is
gesimuleer deur van twee verskillende sagteware pakette gebruik te maak, naamlik eST
Microwave Studio en AWR Microwave Office. Twee filter prototiepes is gebou met silindriese
stafies. 'n Oopgeslote mikrostrook ossilator is ontwerp en geimplementeer deur negatiewe
weerstand te gebruik. Die stelsel se prestasie is bevestig deur gebruik te maak van 'n harmoniese
balans simulator in AWR MWO. Verder is 'n enkelbalans menger ontwerp en geimplimenteer
via 'n 1800 hibriede verbinding ("rat-race"). Hierdie menger is gebou met mikrostrook
transmisielyn. Al die ontwerpte komponente werk goed in vergelyking met die voorspelde
resultate. Die LNA, filter, ossilator en menger word gekoppel en gekarakteriseer as 'n vier blok
stelsel. Die stelsel werk goed behalwe vir 'n skuif in die IF-sein by laer frekwensies a.g.v. belasting.
