A classic and fascinating demo of the mode structure is to glue marshmallows as a solid layer to a piece of cardboard and put it in the oven. The mode pattern gets melted into the stuff.Original poster: Ed Phillips <evp@xxxxxxxxxxx>
If anyone is interested I have a Java program somewhere which plots the electric and/or magnetic fields in a section of waveguide for different ratios of dimensions to each other and to the wavelength. Might be kinda interesting to stick typical MO parameters into it. There will be a question of which modes are excited.
