Electromagnetic Radiation and Scattering of Wire Structures

Electromagnetic radiation and scattering are considered important topics in electrical engineering and technology, and help form the foundation of electromagnetic interference and electromagnetic compatibility. A comprehensive understanding of the radiation and scattering phenomenon will benefit the students who want to be engineers in the fields of RF circuit design, antennas and wireless communications, Radar engineering, and high-speed networking. This paper will discuss the physics of electromagnetic radiation and scattering of wire structures, which can be adopted to understand more complicated applications. After an introduction of the basic theory, discussion of the phenomena from the perspective of engineering is presented. Numerical simulations from time domain will be provided for several fundamental wire structures. This effort fosters the students’ interest in electrical engineering. The University of Southern Mississippi is in the process of enhancing its electronic engineering technology program, and materials presented in this paper will be utilized in the development of future courses.
