hey guys, i have always been interested in the concept of electromagnetic radiation and have been trying to understand it. I havent as yet been able to get information which explains it in any kind of great detail. i have learned the basics like a changing electric field creates a changing magnetic field and all that but what has really mystified me is the differenct types of electromagnetic radiation in that a wave can have one of the fields in the direction of propagation? i saw that there were a few different types and was referenced in info i was looking at describing the use of waveguides.
could anyone explain this to me?
cheers
