Major, Measurable Learning Objectives aving successfully completed this course, the student will be able to: 05 Use the underlying concepts from vector calculus and the major coordinate systems properly alculate the electrostatic fields and capacitance in simple problems, using the theory of electrostatics in materials in general and the Maxwell equations for electrostatics specifically Show how the concept of conduction current relates to circuit problems, and solve problems relating fields to currents efine the Maxwell equations for magnetostatics in materials, and apply these to finding the magnetostatic fields in simple situations 06 enerate the time-dependent Maxwell equations for electrodynamics through araday s law and Maxwell s displacement current Show how these time-dependent equations lead to the concept of waves and develop the basic properties of time-harmonic waves etermine the basic transmission and reflection properties of waves

2 evelop the propagation and impedance equations for transmission lines and solve simple transmission-line problems using a Smith hart efine and categorize the simplest kinds of wave guides PRT. ustification Reason for Teaching the ourse: ll electromagnetic phenomena are based upon the theory of electromagnetic fields, expressed most efficiently for more than one hundred years by Maxwell s equations. The meaning of basic concepts such as voltage, power flux, transmitted and received wave energy, etc., which underlie all of the applications in electrical engineering, cannot be understood without some understanding of Maxwell s equations and their direct consequences. The course stresses the fundamental aspects of electrical engineering in direct conjunction with major applications. Level ustification: The course requires the background of sophomore level courses and begins a new development in the student thought process for visualizing three-dimensional phenomena relevant to electrical engineering. This course is appropriate at the junior level since it covers material necessary for all senior electives in electromagnetics. Modification: Prerequisites to be consistent with departmental curriculum changes, department name, and format. raduate redit: No graduate credit PRT V. Prerequisites and o-requisites Proficiency in differential equations and an introduction to vectors is necessary to understand the motion of charged particles in electromagnetic fields. onsequently, students must have Math 6 or equivalent and Physics 06 as prerequisites.
