Course Objective:



The first course in time varying electromagnetic fields

which

is designed for the undergraduate s
tudents to
make them
understand
the thorough
working knowledge of the rich and varied phenomena of electricity and magnetism

before moving on
to more

advance su
bjects of their interest e.g.

antennas and arrays, microwave engineering
,
radar systems, fiber and integrated optics,
quantum electronics,

po
wer systems, high speed networks,

remote sensing of the environment and wireless communications.


Course Description:


Field theory of electromagnetic phenomena based on vector analytical formulation of fundamental observations, and application

thereof to

electrostatic, magnetostatic and electromagnetic
effects. The

theory of electromagnetism is presented in terms of
Maxwell's Equations.

Regardless of the reason for your absence, it is
your

responsibility to know what assignments, lecture notes, and class
announcements you missed.


Because meeting deadlines is critical in
engineering

profession, the importance of meeting deadlines is stressed in
this course. That means

an assignment handed in after a deadline set by your instructor receives zero points.

If there are any problems with the course or you are having difficulties with the
theory or with the problems, please c
