電磁數值學

Aim of the course: give students knowledge of numerical solutions of electromagnetic wave problems, relevant mathematical theory, and pros & cons of different formulations and software approaches. The course will follow approximately the following tentative syllabus: 1. Review of Electromagnetics Principles a. Integral Equation (IE) Methods b. Introduction to Method of Moment i. Plane wave scattering from wires, strips, cylinders ii. Waveguide Mode Matching c. Spectral Green's Functions for Multilayer Structures d. Waveguide/Cavity Green's Functions 2. Differential Equation (DE) Methods a. Finite Difference Approaches, Finite Difference Time Domain (FDTD) Method b. Finite Element Method 3. High-Frequency Asymptotic Techniques a. Geometrical Optics (GO) Ray Tracing b. Physical Optics (PO) Topics covered in this "Computational Electromagnetics" course include integral equation methods entailing the method of moments and spectral-domain Green's functions for multilayer structures as well as waveguide/cavity Green's functions, and differential equation methods encompassing the finite difference method, finite difference time domain (FDTD) method, and the finite element method (FEM). Foundational electromagnetic principles and concepts such as the duality theorem, uniqueness theorem, image theory, reciprocity theory, the surface equivalence theorem and the physical equivalence theorem, in addition to the fundamental laws of boundary conditions on electromagnetic fields, are all also taught in this course. These are particularly pivotal to the proper learning of the integral equation method (moment method) entailing various types of Green's functions as listed above: a) spectral-domain types for stratified structures and waveguide/cavity types typically useful for closed microwave devices (whose fields are confined within rather than radiated out as would be for antennas).
