Carolina C. Ilie is an Associate Professor with tenure at State University of New York at Oswego. She taught Electromagnetic Theory for almost ten years and she designed various problems for her students' exams, group work and quizzes. Dr. Ilie obtained the Ph.D. in Physics and Astronomy at University of Nebraska at Lincoln, a M.Sc. in Physics at the Ohio State University and another M. Sc. in Physics at University of Bucharest, Romania. She was received the President's Award for Teaching Excellence in 2016 and the Provost Award for Mentoring in Scholarly and Creative Activity in 2013. She lives in Central New York with her spouse, also a physicist, and their two sons. Zachariah S Schrecengost is a State University of New York alumnus. He graduated summa cum laude with a BS degree having completed majors in Physics, Software Engineering, and Applied Mathematics. He took the Advanced Electromagnetic Theory course with Dr Ilie and was thrilled to be involved in creating this book. He brings to the project both the fresh perspective of the student taking electrodynamics, as well as the enthusiasm and talent of an alumnus who is an electrodynamics and upper level mathematics aficionado. Mr Schrecengost works as a software engineer in Syracuse and is preparing to begin his graduate school studies in physics.
