1 1 Numerical ElectroMagnetics & Semiconductor Industrial Applications Ke-Ying Su Ph.D. National Central University Department of Mathematics 02. Method of Moment

2 2 Ke-Ying Su Ph.D. The material is for NCU/MATH course only. Reference : “Field Computation by Moment Methods”, Roger F. Harrington. Concepts of Method of Moment, and basic theory of electrostatic field will be introduced in this class.

3 3 Ke-Ying Su Ph.D. The material is for NCU/MATH course only. Consider an equation Method of Moment is a mathematical technique to reduce a functional equation to a matrix equation. Following is an mathematical example. I. Formulation of Problems

4 4 Ke-Ying Su Ph.D. The material is for NCU/MATH course only. The solution of (1-8) is not unique, until boundary conditions (1-9) are included. Then
