Editorial

Welcome to 2009 and a new issue of IEEE Potentials. I am especially proud to note that three of the technical articles are written by IEEE Fellows and one by a recent doctoral graduate. As always, we have ensured that these articles are geared toward the background and interests of Student Members and entry-level engineers. To our readers who are contemplating their careers and research, we hope these articles will introduce you to new ideas and fields of study; to our readers who are more concerned with their academic coursework, we are confident these articles will give you an opportunity to see the impact of textbook theory to cutting-edge engineering applications.
