Arthur D. Yaghjian works primarily as a research engineer in the area of electromagnetic theory. His work has led to the determination of electric and magnetic fields in natural materials and metamaterials, as well as to the development of exact, numerical, and high-frequency methods for predicting and measuring the near and far fields of antennas and scatterers in both the time and frequency domains. His contributions to the determination of the classical equations of motion of accelerated charged particles have found recognition in a number of texts such as the latest edition of Jackson's "Classical Electrodynamics." He has published two books, several chapters in other books, and about 120 archival journal articles, four of which received IEEE best paper awards. He is an IEEE Life Fellow, has received an Honorary Doctorate from the Technical University of Denmark, the IEEE Electromagnetics Award, the IEEE-APS Distinguished Achievement Award, and has served as an IEEE-APS Distinguished Lecturer.
