Welcome to Physics 442!

Winter 2020

- Direct link to our class on Max: https://max.byu.edu/20201-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.

- From last semester: Parallel Equations for the Electric and Magnetic Fields.pdf
- lecture 1 - Ohm's law.pdf
- lecture 10 - Complex wave number.pdf
- lecture 11 - Lorentz oscillator model.pdf
- lecture 13 - TE modes of rectangular waveguide.pdf
- lecture 13 - Bessel functions.pdf
- lecture 14 - cylindrical waveguides.pdf
- lecture 14 - TM Modes of a Cylindrical Waveguide.pdf

Here are handouts from my last 442 class, which may be modified this semester (but which likely will be similar).

- lecture 32 - 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 32 - Skew Lines for Relativity.nb (Mathematica)
- lecture 41 - proof of field tensor transformation.nb
