CMPE 330:
Electromagnetic
Waves and Transmission

Catalog description:

An introduction to waves, transmission lines, and electromagnetics
is made with the focus on computer engineering and communications applications. The
physical limits on Kirchhoff’s
Laws are discussed. Phasor
and vector
analysis is
reviewed. Transmission lines are studied in the time domain and the frequency domain.
Elect
rostatics, magnetostatics, and the calculation of the capacitance and inductance in
transmission lines are then
studied. Time
-
varying fields, and the integral, differential,
and phasor forms of Maxwell’s equations are introduced. Plane waves are studied.
