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

Final Grade Breakdown:

 

Iowa State University is committed to assuring that all educational activities are free from discrimination and harassment based on disability status. All students requesting accommodations are required to meet with staff in Student Disability Resources (SDR) to establish eligibility. A Student Academic Accommodation Request (SAAR) form will be provided to eligible students. The provision of reasonable accommodations in this course will be arranged after timely delivery of the SAAR form to the instructor. Students are encouraged to deliver completed SAAR forms as early in the semester as possible. SDR, a unit in the Dean of Students Office, is located in room 1076, Student Services Building or online at www.dso.iastate.edu/dr/.
