COURSE COMPACT
SECTION 1: Review of Vector Algebra & Calculus
OBJECTIVES: At the end the students should have a deep understanding of Vector Algebra,
Vector Analysis and Vector Calculus needed for solving problems in Electromagnetics
OUTLINE: Scalar product and vector product, coordinate systems, gradient, curl, divergence
operations. Gauss’s, Stokes, Helmholtz and Green’s integral theorems, integral of scalar and
vector fields.
SECTION 2: Electrostatics
OBJECTION: In this section, the students are introduced to the fundamental concepts of the
course. At the end of the section the students should have a good understanding of the laws
governing static charges as obtained in Electrostatics. Students should be able to use the laws
of electrostatics like Coulomb’s and Gauss Law in solving problems in Electrostatic Fields. They
should be acquainted with fundamental Theorems like Stokes’ and Divergence used in
mathematical simplification.
OUTLINE: Charge and charge density. Coulomb’s Law. Concept of fields. Electric flux density and
electric field intensity. Gauss’s Theorem and applications. Voltage and electric potential.
Conductor, dielectrics. Polarization, susceptibility, permittivity. Electrostatic boundary
condition. Capacitance calculation and electric energy
SECTION 3: MAGNETOSTATICS
OBJECTIVE: Magnetostatics introduces students to the other half of Electromagnetics. At the
end of this section students should understand the duality of the electromagnetic
phenomenon. They should understand that it is a steady current that gives rise to a Magneto
static fields, and not a magnetic charge, as in the case of electrostatics .They should be able to
see the similarity between the Biot- Savart and Ampere’s Law with Coulomb’s and Gauss’ laws
in electrostatics
OUTLINE: Current and current density. Magnetic dipoles and current loops. Magnetic flux
density and magnetic field intensity. Biot-Savart Law and Ampere’s Law, Faraday’s Law.
Magnetostatic boundary condition. Self and mutual induction. Inductance calculation and
magnetic energy.
SECTION 4. Maxwell’s Equations
OBJECTIVE: In this section student will be introduced to one of the most important concepts of
Communication fundamentals- the Maxwell’s equations. Student should be able to appreciate
Maxwell’s equation for its usefulness in explaining Faraday’sand Ampere’s law
OUTLINE: Time Varying fields: Faraday’s Law of Induction, the conservation of charge and the
incompleteness of Ampere’s Law. Maxwell’s equations and Lorentz force law. Uniform plane
waves and wave equation. Time harmonic fields. Polarization of waves. Poynting’s Theorem and
the conservation of energy, the field definitions of impedance, admittance. Phase and group
velocities
SECTION 5: WAVES IN MEDIA
OBJECTIVES: In this section, students are introduced to the propagation of waves in different
media other than free space. They should understand how Maxwell’s equation could be applied
in solving problems of dielectrics and permeability.
OUTLINE: : lossy media, dispersive media. Wave Propagation and Transmission Theory:
Boundary conditions. Reflection and refraction at plane interface (normal and oblique angles),
transmission line analogy
SECTION 6: TRANSMISSION LINE THEORY
OBJECTIVE: In this section, students are introduced into the concept of transmission line,
differentiate the analysis of lines operating at normal frequency as seen in circuit theory from
lines operating at high frequencies. They should also be able to use the Smith Chart in solving
transmission line problems.
OUTLINE: differential equations for a general transmission line, low loss and lossless lines,
impedance characteristics of lines with various terminations, simple mismatch problems and
the use of Smith Chart. Introduction to Waveguides and Cavity Resonators
