Polarization Animation and PLF Calculation (5/2/2026)

The Matlab Live Script (mlx-file) that I used in class to animate transmit and receive electric field vectors with user-selected polarizations and to calculate the polarization loss factor (PLF) is now available at the course Moodle site in the "Matlab Files" section.

To run the script, copy the mlx-file into a directory on your computer or in your private Netspace and then double click on the filename. Matlab should start up automatically, and the mlx-file should appear in the editor window. After you have defined the transmit and receive electric fields, click on the "Run" button in the upper right part of the ribbon at the top of the window. You will probably have to scroll down the window to see the animation. If you change either polarization, you will probably have to click on the "Stop" and then "Run" buttons to execute the animation with the new settings.
