- Direct link to our class on Max: https://max.byu.edu/20191-phscs442/

- Here's the "n_of_air.txt" file that you need for one HW problem: n_of_air.txt
- Here's the Mathematica code to generate zeroes of the Bessel derivative functions (open, then copy and paste into your own notebook): besselprimezeroes.nb
- Here's the graph paper you need for the "graphical Lorentz transformation" HW problem: graphical_velocity_transformation.pdf

- The syllabus and tentative schedule is available on Max. If you'd like a hardcopy you'll to print that out yourself..

Here are handouts for/from various class periods, to be updated throughout the semester.

- lecture 1 - Parallel Equations for the Electric and Magnetic Fields.pdf
- lecture 11 - Lorentz model derivation.pdf
- lecture 12 - The Power of the Lorentz Model.pdf
- lecture 13 - TE modes of rectangular waveguide.pdf
- lecture 13 - Bessel functions.pdf
- lecture 14 - TM Modes of a Cylindrical Waveguide.pdf

Old links from last semester; probably the handouts for this semester will be quite similar.

- lecture 33 - Lorentz transformations Labview program: lorentz.exe. Requires you to install this Labview "run time engine": http://www.ni.com/download/labview-run-time-engine-8.6.1/1244/en/.
- lecture 42 - proof of field tensor transformation.nb
