High power electromagnetic pulses are of great importance in a variety of
applications such as transient radar, investigations of the effect of strong radio-frequency
impulses on electronic systems and modem bio-medical technology. In response to the current
trend, a simple, compact, and portable electromagnetic pulse (EMP) radiating source has been
developed, based on pulsed transformer technology and capable of producing nanosecond risetime pulses at voltages exceeding 0.5 MY. For this type of application pulsed transformer
technology offers a number of significant advantages over the use of a Marx generator, e.g.
design simplicity, compactness and cost effectiveness. The transformer is operated in a dual
resonance mode to achieve a high energy transfer efficiency, and although the output voltage
inevitably has a slower rise-time than that of a Marx generator, this can be improved by the use
of a pulse forming line in conjunction with a fast spark-gap switch.
The transformer design is best achieved using a filamentary modeling technique,
that takes full account of bulk skin and proximity effects and accurately predicts the self and
mutual inductances and winding resistances of the transformer. One main objective of the
present research was to achieve a high-average radiated power, for which the radiator has to be
operated at a high pulse repetition frequency (PRF), with the key component for achieving this
being the spark-gap switch in the primary circuit of the pulsed transformer. Normally a sparkgap switch has a recovery time of about ten milliseconds, and a PRF above 100 Hz is difficult to
achieve unless certain special techniques are employed.
As the aim of the present study is to develop a compact system, the use of a
pump for providing a fluid flow between the electrodes of the spark gap is iii Abstract ruled out,
and a novel spark-gap switch was therefore developed based on the principle of coronastabilization. For simplicity, an omnidirectional dipole-type structure was used as a transmitting
antenna. Radiated electric field measurements were performed using a time-derivative sensor,
with data being collected by a suitable fast digitizing oscilloscope. Post-numerical processing of
the collected data was necessary to remove the ground reflected wave effect. Measurements of
the radiated electric field at 10 m from the radiating element indicated a peak amplitude of 12.4
kV/m. Much of the work detailed in the thesis has already been presented in peer review
