30.102 Electromagnetics & Applications

Home / Education / Undergraduate / Courses / 30.102 Electromagnetics & Applications

This course focuses on electromagnetics (EM, Maxwell equations), the theories and applications. It includes

  • Transmission line theory and circuit concepts of EM waves
  • Resonators and waveguides
  • Antennas
  • Plane waves
  • Waves in different media and boundaries

The hands-on sections cover Matlab programming and commercial EM software (CST microwave studio). 1D project this year is wireless power transfer. 2D project is to apply EM to solve problems related to another discipline. The content from Physics 2 (10.005) will be recapped.


  • Maths 1
  • Maths 2
  • Physics 2
