Phys.422 Electrodynamics 3+1*

LEARNING OBJECTIVES:

The primary aim of this course is to:
 Maxwell‘s theory of electromagnetic phenomenon is a basic component of all modern
courses of theoretical physics and all students of physics must have a thorough knowledge
of its principles and working.
 The basic ingredient of this theory is the concept of a field and the equations which govern
the space and time evolution of these fields.
 These fields are called electromagnetic fields and the equations are known as the Maxwell
equations.
 Moreover, these fields show a wave behaviour and are termed as electromagnetic waves.
Visible light is an example of electromagnetic wave.
 In this course, we shall learn about the working and applications of the Maxwell equations
and how it is consistent with the theory of relativity.
 One of the objectives of this course is to introduce students with the formulation of four
vectors. They are to be introduced by the Lorentz transformations and the invariance of
various quantities in four dimensions.
 Main aim is to feed student‘s mind by fields and radiations from various types of dipoles
and localized sources. They will be taught to calculate power radiated in each case.
 Students will be introduced by the formation and characteristics of ionosphere and how
waves propagate through it.
 The objective is to introduce them about wave guides and their applications.
 They will be taught about the transmission lines and propagation of waves through them.

LEARNING OUTCOMES:

After successful completion of this course, students shall be able to:
 Evaluate the electrostatic fields and potential in free space and in a dielectric media.
 Evaluate configuration energy of an electrostatic system.
 Understand the production of magnetic field due to steady current and calculate magnetic
fields using Boit Savart and Amperes law.
 Understand the Maxwell‘s equation of electrodynamics and its applications to propagation
of electromagnetic waves.
 Understand the concept of wave guide and basic concept of plasma and confinement.
