Wave Propagation in periodic structures (Summer Semester 2022)

  • Lecturer: Dr. Ruming Zhang
  • Classes: Lecture (0173800), Problem class (0173810)
  • Weekly hours: 2+1

This lecture introduces theoretical analysis and numerical methods to simulate wave propagation in periodic structures. This is an interesting topic in both mathematics and other areas, such as nano-technology. In this lecture, we will study the well-posedness of this kind of problems and discuss the properties of the solutions. We will also introduce numerical methods to simulation the physical processes.

Preliminary course: functional analysis, partial differential equation, numerical analysis. However, we will review some important definitions and results at the beginning of this lecture.

For a better understanding of the wave propagations, I will share some MATLAB codes and figures corresponding to the contents. Students are also encouraged to write their own codes.
