Course Objectives - As part of this course, students:

  1. develop an understanding of the fundamental concepts of electromagnetic fields, with an emphasis on wave propagation. [6]
  2. relate basic electromagnetic concepts to the performance of devices, circuits, and systems. [6,8]
Course Outcomes - Upon successful completion of this course, students should be able to:

  1. determine parameters associated with waves on lossless and lossy transmission lines, including frequency, phase velocity, attenuation and phase consts
  2. solve transient problems involving initially uncharged or charged transmission lines with resistive and reactive loads
  3. design transmission line terminations to minimize reflections and maximize received power
  4. explain the fundamental processes by which crosstalk between transmission lines occurs
  5. determine frequency-domain parameters associated with a transmission line system, including input impedance, reflection coefficient, and SWR
  6. analyze transmission line problems in the frequency domain with complex load impedances, to determine input and load voltage/current, power delivered
  7. calculate the electric field, scalar potential, stored energy, and capacitance associated with simple distributions of charge
  8. calculate the magnetic field, stored energy, and inductance for simple distributions of current density
  9. calculate the resistance of simple structures of given conductivity
  10. apply boundary conditions to determine current and charge densities produced on conducting boundaries by applied fields
  11. identify Maxwell's equations and apply them in both their integral and differential forms to time-varying field problems
  12. identify an electromagnetic wave and determine parameters (frequency, phase constant and velocity, associated intrinsic impedance) and power density
  13. determine the attenuation constant, phase constant, and skin depth for waves in a lossy medium, where the conductivity may range from low to high
  14. distinguish between linear polarization, circular polarization, and elliptical polarization with right-hand/left-hand orientation
  15. calculate reflection and transmission coefficients and fields for uniform plane waves normally-incident and obliquely-incident on planar interfaces
