Unformatted text preview: tions centered around the origin, but centered around dierent k in the Fourier transform. What happens to the wave packets after suciently long time in free space and in the wave guide? For your handing in, please provide the analytic form of the physical wave (real valued amplitude, and initial time derivative), the complex valued initial function for the eld. All with a suitable set of parameters. Also add a print-out of your short code. Provide plots for t=0 and suitable chosen follow-up times to show how the pulse propagates in time. Remark: with the mathematics packages it should not be too hard to im-plement the numerics with the standard mathematics tools, but you will have to spend some thought to nd which parameter regime which demonstrates the expected eects without running into numerical problems. 1...
