Instructor: Jiming Song

Office Hours: Coover 2130, Tuesday and Thursday, 1-2pm


Course Description

(3-0) Cr. 3. F. Prereq: E E 311

Review of static electric and magnetic fields. Maxwell's equations. Circuit concepts and impedance elements. Propagation and reflection of plane waves in isotropic media. Guided electromagnetic wave. Characteristics of common waveguides and transmission lines. Propagation in anisotropic media. Special theorems and concepts. Radiation and scattering.


Learning Objectives

  1. Derive Maxwell equations from integral form to differential form and the boundary conditions
  2. Define the phasor form, calculate Poynting power flow vector, confirm the energy/power conservation
  3. Define polarizations: linear, circular, and ecliptic, find polarization status for given plane waves
  4. Apply approaches for transmission lines to solve wave propagation in multilayered media
  5. Find waves propagating in plasma, uniaxial medium, and metamaterials
  6. Define vector and scalar potentials and find them
  7. Define the far field condition. Given electric sources such as dipole, loops, and apertures, find the far field
  8. Apply Huygens principle and equivalent sources to find approximated solutions for simple objects
  9. Given dimensions of rectangular and circular waveguides, find the cut-off frequency, propagation constant, and wave impedance. For cavities, find resonant frequency.
  10. Define the radar cross section (RCS), find the scattering from circular cylinder and sphere, and high frequency and low frequency limits


Textbook, References, and Notes

Homework: Homework assignments will be given every Thursday and are due exactly a week later for on-campus students. The off-campus students have 5 more days.

There are two project assignments.

The last homework assignment and the second project are due in the last class (dead week).
