Detailed Description and Outline

Topics:

Lorentz force relation; electrical and magnetic polarizations and constitutive parameters; electric and magnetic currents and conductivity parameters; boundary conditions at the interface between two media and across surface currents; Poynting theorem in real and complex forms and energy relations; complex permittivity and permeability

Plane wave: in homogeneous media: reduction to vector Helmholtz equation; separation of variables; uniform and nonuniform plane waves; wave impedance; reflection and refraction at oblique incidence; fields of infinite current sheets; polarization properties of waves

Fields in waveguides: dispersion; phase, group and energy velocities; attenuation; resonant cavity; inhomogeneously filled waveguides; transverse resonance

Antennas: dipoles; radiation patterns; approximate analysis of some antennas
