Course Type/Credits: Elective course/3 credits
Review of electromagnetics and Maxwell’s equations; finite differencing of partial differential equations; one-dimensional wave equation; the finite-difference time-domain (FDTD) method; numerical stability and dispersion; scattered field formulation; absorbing boundary conditions; method of moments (MoM); finite element method (FEM).
This course examines the principles and applications of numerical techniques for solving practical electromagnetics problems. By the end of this course the student will be able to:
- Understand why numerical methods are needed to solve realistic or practical problems in electromagnetics and why this need will increase.
- Understand the mathematical concepts upon which computational electromagnetics relies.
- Can translate the mathematical description of a solution into a computer program.
- Can choose between the various numerical methods to use the right method for a particular problem.
- Develop a foundation level necessary for successful use of available computational EM tools (programs such as HFSS, Momentum, and others) for research in the area of numerical and applied electromagnetics.
