A review sheet handout and any handwritten notes on it, a writing utensil and a calculator will be allowed for exams; NOTHING else will be. Please note that there is absolutely no provision in this course for extra credit assignments of any sort.

Overall Educational Goals: ECE 381 is structured to provide all students with the fundamental concepts and analytical techniques associated with electromagnetics and transmission line theory. Successful completion of this course will allow a student access to all of the 400 level tech electives in the electromagnetics and optics areas. Students completing this course are expected to have a good understanding of the fundamental concepts and analytical techniques associated with electromagnetics, including transmission lines. Emphasis is given not only to static situations but also to time-varying, dynamic systems. Connections between the fields approach and circuit models in particular frequency limits are also shown, as well as real world applications of electromagnetics. Specific Learning Objectives: By the end of the course students are expected to be able to: •Perform vector calculus operations such as the gradient, the divergence and the curl. •Identify and list Maxwell’s equations in time domain, as well as associated boundary conditions. •Apply Coulomb’s law to find the force on a charge caused by other charges. •Apply Gauss’ law to determine the electric field caused by a simple charge distribution. •Calculate the electrostatic potential of simple charge distributions. •Explain the effects of conducting and dielectric materials on field quantities. •List the boundary conditions for the electric field vectors on the interface of two different materials. •Calculate the energy stored in an electrostatic field. •Identify Poisson’s and Laplace’s equations and solve them to find electrostatic potentials and fields. •Calculate the capacitance for basic configurations that reduce to one-dimensional systems. •Apply the method of images to find electrostatic potentials and fields of simple charge distributions above perfect conductors. •Describe the conservation of charge and Ohm’s laws and write them in vector calculus format. •Apply Ampere’s force law to calculate the force between constant currents of simple configurations. •Apply the Biot-Savart law to calculate the magnetic flux density caused by a simple current configuration. •Apply Ampere’s law to calculate the magnetic field produced by simple current configurations. •Identify the magnetostatic potential and flux. •Identify and list different magnetic materials. •List the boundary conditions for the magnetic field vectors on the interface of two different materials. •Calculate the inductance and resistance for simple actual physical devices. •Calculate the energy stored in a magnetostatic field. •Identify the time-varying Faraday and Ampere laws (quasi-statics). •Calculate the induction effects from time-varying magnetic fields.
