Acknowledgements

I would like to express my sincere thanks to Mr John Wicking. Without his invaluable advice and direction, this thesis project would not have been possible. I would also like to thank the ECE technical staff, whose immeasurable knowledge, experience, and common sense have saved me from many headaches.

To my friends, for sharing in the insane antics which have helped me maintain my humanity and sense of humour throughout this year, and for reminding me that there is more to life than thesis.

Finally, to my family, for supporting and encouraging me through the greater part of my life.
