L -- Intro to FDTD

This information is needed for Lab 4.   There is no assignment today, but do the prelab for Lab 4.

Video Lectures: Watch before class

• Power Point to take notes on: Lab4 FDTD.ppt Download Lab4 FDTD.ppt

Optional additional reference material:

More detailed FDTD Lectures (These are for E,H equations instead of V,I, and done (initially) in 3D)

Applications:  FDTD is used to calculate fields for almost any application.  Here is an example of some of the early work we did on cell phones (see Marriott Library Reserves or go to IEEE Xplorer online Links to an external site. at the Marriott Library)
