Module I
Coulomb’s law – application. Electrostatic potential, Poisson and Laplace equations, Conductors in electrostatic
field, dielectrics in static electric field. Capacitance, capacitor- examples, boundary conditions, capacitors of mixed
dielectrics and of complex shapes. Energy stored in electric field, Magneto static fields – Biot-Savart’s law,
Ampere’s law – applications, Inductance, energy stored in magnetic field, Magnetic scalar potential. Magnetic
vector potential.
Maxwell’s equations, consequences of Maxwell’s equations, Boundary conditions, Flow of energy in
electromagnetic system, Poynting vector, Complex Poynting vector.
Module II
Electromagnetic waves – Uniform plain EM wave in free space. Propagation of plane EM wave in perfect, in lossless
non-conductors, in conducting media, in good conductors. Reflection and refraction of plane electromagnetic
waves at boundaries for normal & oblique incidence – Snell’s law of refraction, Brewster angle.Uniform Transmission lines – lossless lines. Reflection and transmission at the end of a line. Reflection and
transmission at a discontinuity on the line. Lossless transmission lines with sinusoidal voltage sources. Reflection,
SWR.
Module III
Impedance matching using stub – lines, half wave transformer, quarter wave transformer. Lines with losses – DC
line, low frequency line, high frequency line, Smith chart. The hollow rectangular wave guide – modes of
propagation of wave, dominant mode, calculation of attenuation in wave guides, Intrinsic Characteristics, Wave
impedance. Cylindrical wave guides- TE wave, attenuation. Q factor of wave guides
