Pre-requisite(s) Electromagnetic Theory
Required Facilities Computer Usage:
For electrical field analysis, students are going to use analytic methods and the finite difference method.

Teaching Techniques:
Classroom instruction includes a tutorial. Students are encouraged to contact the instructor for discussing points they find difficult to understand. Labs and visits will be assigned to reinforce the practical skills for the students.
