Downloads for HW problems

Here are some files you will need for some HW problems.

• n-of-air.txt
• besselprimezeroes.nb - Mathematica code to generate zeroes of the Bessel derivative functions (open, then copy and paste into your own notebook)
• graphical-velocity-transformation.pdf - Graph paper you will need for the "graphical Lorentz transformation" HW problem

Handouts

Here are some handouts I have prepared to help clarify or add information on several selected topics.

From Physics 441:

• Griffiths-front-and-back-covers.pdf
• Parallel-Equations-for-the-Electric-and-Magnetic-Fields.pdf - List of most of the important equations in Phys 441, organized according to electric and magnetic field versions of similar equations

From Physics 442:

• Physics-442-Formula-Sheet.pdf - This is the one you should print out, handwrite anything else you'd like on it, and bring to the Testing Center for the exams. You won't need the second page for anything but the final exam (but print out this sheet double sided, then).
• Most-important-equations-of-Physics-442.pdf - Very similar to the Physics 442 Formula Sheet, but with more explanations and a few more equations.
• Ohm-s-law.pdf (approx. lecture 1)
• Poynting-s-theorem.pdf (approx lecture 3)
• Polarization-animations.nb - Mathematica program adding together vertical and horizontally polarized waves with possible phase shifts to get linear, circular, or elliptical (approx lecture 7)
• Complex-wave-number-index-of-refraction-and-relative-permittivity.pdf (approx lecture 10)
• Lorentz-oscillator-model.pdf - Lorentz oscillator model (approximately lecture 11)
• TE-modes-of-rectangular-waveguide.pdf (approximately lecture 13)
• Bessel-functions.pdf (approximately lecture 14)
• cylindrical-waveguides.pdf (approximately lecture 14)
• TM-Modes-of-a-Cylindrical-Waveguide.pdf (approximately lecture 14)
• lorentz-transformations.nb - Lorentz transformations Mathematica program (approximately lecture 31)
• Skew-Lines-for-Relativity.nb - Mathematica program demonstrating constant position and constant time lines (approximately lecture 34)
• magnetic-field-via-relativity.pdf (approximately lecture 27)
• proof-of-field-tensor-transformation.nb - Mathematica program to proof that the field tensor does in fact transform as a rank 2 tensor (approximately lecture 39)
