Two-Dimensional Finite-Difference Time-Domain (FDTD) with MATLAB
Visually learn the formulation and implementation of two-dimensional finite-difference time-domain (FDTD). See every line of code in MATLAB explained by the EMProfessor.
Do you have ideas or designs that you would like to simulate but don't know how to start?
Are you ready to rise above your competition with stunning simulations and visualizations?
This course will give you the ability to derive all the equations for 2D FDTD and implement them in MATLAB. Imagine developing a code that gives you simulation capabilities way beyond commercial software. Learn the powerful "2x grid" method for modeling curved dielectric structures. Learn a unique implementation of the total-field/scattered-field technique to launch sources into your simulations and examine the scattered waves. Learn the state-of-the-art convolutional perfectly matched layer absorbing boundary. And so much more!
Building on the prerequisite course on 1D FDTD, this course will introduce you to 2D simulations and cover everything from deriving all of the equations to writing the programs in MATLAB. The course uses stunning visuals and animations to teach the concepts. The course will step you line-by-line through guided code development and through multiple device examples. You will simulate a grating and calculate the diffraction efficiencies of the diffraction orders. You will learn how to simulate a guided-mode resonance filter as well as simulate a hexagonal photonic crystal. For each example, you will learn the theory of the device and the methodology used to simulate the devices. After hearing Dr. Rumpf's clear and step-by-step explanations, you will be able to simulate your own devices in no time!

Read MoreTo whom who may concern, I discovered this online lecture from a recommendation. Before the discover of these lectures, I had an extremely hard moment to start to learn about the FDTD method. I knew about the electromagnetic theory, I knew about the programmation in Matlab and I thought that I am ready to start the FDTD code in Matlab but I wickly recognized that still not enough because I don't know about the specific technics in FDTD such as 2x grids, incorporation of PML, incorporation TF/SF in Yee grid. I spent a lot of time to do the research on the Internet but I found very few doccumentations that could respond to my problem and my need in FDTD method. Up to now, these 2D FDTD lectures are the only open source on the Internet that help me to master the FDTD method. I am not only learn from Dr Rumpf the code in Matlab but also the mathematics development of FDTD. After these lectures, I feel like I am ready to apply my knowledge in FDTD into my future projects which involve the modelization of light-matter interactions. I really want to learn more from Dr Rumpf on the advance topics in FDTD such as the problem of frequency-dependance materials, Near Field to Far Field technic, Scattering analysis, anisotropic materials and 3D FDTD. Thanks you a lot for your amazing lectures and I look forward to learn from you about the advance topics in FDTD soon. Your online student, HUYNH Thanh Trung
