In the name of Allah, the all mighty god, the one and only one, I hereby start my thesis.
Praises to Allah, for his mercy upon me. For his generous gifts of health and brain which allowed me to proceed higher studies at one of the best universities in the world, University of Tokyo.
Praises to Allah, for gifting me with a perfect wife, my supporter through this journey. Thank you Randa for all your support and your cheers through the difficult times of research. Thank you, for your acceptance to accompany me in Japan, while you knew I will always be busy, away from you, working in my laboratory. You went through a hard time, spending most of your time alone while I progressed in my research connecting days with nights, but you only greet me with a smile and a welcoming heart, when I knock your door. Thank you, for making your house, my home.
I deeply thank and raise the hat for my supervising professor, Prof. Ikeda for his continuous teaching and support. Each time I sit with him, I gain a huge amount of knowledge not only in my research field but also in life. His welcoming helped me to settle in Japan and feel it like home, while His teaching provided me with solid knowledge and helped me to become a better Electrical Engineer. This work could have never been achieved except for the guidance I received from him.
I also thank Prof. Asada for his guidance and support throughout the research, and his fatherly advices to help me become a better researcher. All the thanks for Prof. Nakura for his help during my experimental research and measurement. He was always open for any questions, and his words were fulfilling answers.
My appreciation and respect for Dr. Abbas, for his support. He tended to calm me down during rough times, and his experience in our field could help me through complicated situations by providing me his suggestions. He is like an older brother, always there when you need him. I also thank Dr. James Tandon for his support during the start my Masters, and for his precious advices.
I send my thanks to Jordan, for Dr. Khamis, for his fatherly support and help in any matter I need, and for Dr. Yaser for helping me when I got married and supporting me like his son.
I thank all my lab members and research-mates for the friendly environment and healthy atmosphere that makes research and creativity easier.
In addition, I can never forget the trust of Yamashita-san, or the faith of Kobayashi-sensei in me. I can never forget how Taymour-sensei helped choose my desired field, or how Saqf-san helped me through the difficult transition of starting a new life in Japan.
Finally, no words can describe my appreciation for my father, god bless his soul, who wished before he died to see me holding a higher education degree. And my mother, who provided me with everything I needed since I was a child until I left the house coming to Japan. Without her, getting a professional degree would have been impossible. I thank her for all the prayers she has made to help me through my research.
