For graduate level courses, the following are suitable exercises. Most have been tested over the years by the author in a classroom environment. The approximate time required by a student to complete the assignment is also indicated, to assist in planning. This must be treated as only a guideline; it can change significantly, perhaps by as much as a factor of two either way, depending in particular on the programming ability of students or their familiarity with a particular code. The times given are for code development from scratch, and are based on the time the author and/or typical students have spent developing the routines or models; if some existing material is made available to the students, these can be greatly reduced. A number of MATLAB files,. pre files etc. are available to assist readers.

Chapter 2

1D FDTD analysis

1. Write a program to implement the 1D FDTD analysis of a transmission line, as discussed in this chapter. In particular, repeat the results given for the single-frequency source (Fig. 2.6), and also for the wideband source (Figs. 2.20, 2.21 and 2.22). Also investigate the effects of other termination conditions, such as a matched load. [20 hours]

Chapter 3

2D FDTD analysis

1. Repeat the TEz scattering analysis discussed in this chapter using longer (in time) pulses and shorter pulses. Explain the time domain results obtained with each of these. Keep the grid size at 800 × 400 and M = 1024 so that run-times remain minutes rather than hours. [20-30 hours]

2. Modify the code to compute TMz scattering from a cylinder. Does the TMz polarization also show creeping waves? [10 hours]
