About This Course

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!
