A novel combustion chamber has been developed for determining the value of the minimum ignition energy at S-band for different mixtures of gases. Therefore, the author designed a re-entrant symmetrical cylindrical cavity resonator to find the real value of the minimum ignition energy and to predict the worst case incendivities. Chapter 1 introduces the factors affecting the incendivities of the microwave breakdown sparks. In Chapter 2 the relevant value of the electrical parameters of the ignition chamber (cavity resonator) are computed from the classical successive over-relaxation (SOR) method. Chapter 3 shows a series of experimental work which has been done to measure the ignition cell's electrical parameters for comparison with theoretical computation. Most of the experimental work is discussed in Chapter 4 to measure the probability of breakdown sparks and leads on to Chapter 5 to find the real value of the minimum ignition energy (MIE) for the mixtures of gases (hydrogen, ethylene, acetylene and ethane with air). Finally, Chapter 6 is written to gather some conclusions and to make proposals for future investigations.
