hello everyone my name is pradeep kumar k
and i am a faculty in the department of electrical
engineering at iit kanpur this course is electromagnetic
theory one of the core courses taken by students
in electrical engineering electronics and
communication engineering and telecommunication
engineering typically in your third or second
year if you complete this course successfully
you will be able to do ah much well in the
higher ah level courses such as microwave
engineering radars antenna and optical fiber
and optical communications
now there is no exaggeration when i say that
we live in an electromagnetic age right from
an inverter or right from the power generation
system to the high end high speed digital
computers or computing device or a smartphone
you will see the principles of electromagnetics
being applied everywhere ok
electromagnetics is the study of how charge
distributions and currents generate various
fields and how these fields themselves interact
and how we are going to harness this electromagnetic
energy in generation propagation and radiation
ok so this course is a kind of core curriculum
for all these engineering students and the
course starts with static electric field progresses
to static magnetic field talks about electromagnetic
induction and finally culminates in maxwells
equations which is a historic triumph for
physics and forms the cornerstone for electromagnetic
engineering applications
we will then discuss various aspects of electromagnetic
energy related to propagation and radiation
we will discuss transmission lines which are
extremely important if you want to design
high speed digital or analog systems we will
discuss microwave engineering concepts ah
such as waveguides we will also discuss optical
fibers which are the way in which data is
carried today so if you understand optical
fibers thoroughly after understanding electro
magnetics then you can ah perform very well
in that particular subject and finally we
will touch briefly upon radiation which is
how an antenna radiates we will study how
an antenna radiates energy into space and
antennas as you know are the mainstay of wireless
communications
we will not assume any background except a
background with differential equations differential
ah integral ah integral so ah evaluating the
integrals i will introduce vector concepts
as necessary as we go along the course ok
so you dont have to know vector analysis before
hand however if you know vector analysis some
of these concepts might become very simple
to you however if you dont have vector analysis
background this is a good area to learn vector
analysis and vector calculus some of these
topics will be further useful to you in various
other branches of engineering
so we will introduce vector calculus as and
when required we start from coulombs law end
at maxwells equations that will be our first
ah part of the course in the second part of
course we take electromagnetic we we take
maxwells equations and then start applying
it to different physical scenarios and discuss
ah microwave engineering we discuss transmission
lines radiation and optical fibres the course
is forty hours ah i will also give appropriate
course materials ah we will also introduce
some numerical methods to the course i will
discuss how to obtain capacitance and inductance
of practical structures using numerical methods
and important aspect of this particular course
is that we will also introduce what is called
as quasi static analysis which is a half way
between stationary and non stationary electromagnetics
that is between time invariant or static and
time varying electromagnetic fields knowledge
of this will really help you in ah performing
well in other courses as i have mentioned
