Course Description
A study of current techniques employed to solve practical electro-magnetic field problems.
Emphasis will be placed upon antenna and radar cross section problems using moment methods.
Students will be expected to use the techniques treated to solve problems using a digital
computer.
Prerequisites
Students taking this course should understand the material in ECE 471, an intermediate level
course in Electromagnetic Waves and Fields dealing with time varying fields and waves. They
should have had ECE 671 or ECE 674 or an equivalent course.
Text
There is no prescribed text for this course. Several journal articles and some chapters from the
following book will be used as reference material.
