EECS 309 Electromagnetic Fields (Spring 2012, Spring 2013, Spring 2014, Spring 2015, Spring 2016, Spring 2017)

Textbooks:

  1. Branislav M. Notaros, Electromagnetics , Prentice Hall, 2010.
  2. Nathan Ida, Engineering Electromagnetics (Second Edition) , Springer, 2004.
  3. Clayton R. Paul, Electromagnetics for Engineers with Applications , Wiley, 2004.
  4. Hongping Zhao, Lecture Notes on Electromagnetic Fields.

Course abstract: First part of the course covers the electrostatic and magneticstatic, with an emphasis on the introduction of the general concepts of Gauss’ Law, Ampere’s Law and Ohm’s Law. Second part of the course emphasizes on the electromagnetic waves. We develop the theory of how time-varying EM waves move in media. The dynamical property of EM waves is governed by Maxwell’s equation. We also present the relevance of EM theory in the modern applications through the course, in particular in wireless communications, optical communications, photonics, optoelectronics, nanophotonics, and biotechnology. If time permits, main applications of EM theory in transmission line, waveguides and resonators, as well as antennas, will be introduced.

EECS 329/429 Introduction to Nanomaterials: Material Synthesis, Properties and Device Applications (Fall 2014, Fall 2015, Fall 2016)

Textbooks:

  1. Omar Manareh, Introduction to Nanomaterials and Devices, John Wiley & Sons.
  2. Hongping Zhao, Additional Lecture Notes

Course abstract: The behavior of nanoscale materials is close, to atomic behavior rather than that of bulk materials. The growth of nanomaterials, such as quantum dots, has the tendency to be viewed as an art rather than science. These nanostructures have changed our view of Nature. This course is designed to provide an introduction to nanomaterials and devices to both senior undergraduate and graduate students in engineering. Topics covered include an introduction to growth issues, quantum mechanics, quantization of electronic energy levels in periodic potentials, tunneling, distribution functions and density of states, optical and electronic properties, and devices.
