HI guys, ok i have started college and have a pretty scatty physics teacher...
He was demonstrating for us how a structure of parallel metal bars can polarise microwaves. What i was trying to ask him is, if the metal bars can stop the electric aspect of the waves, how do they not stop the magnetic aspect? I mean the magnetic field is dynamic in nature, surely this would induce a current in the metal and just short it out?
Thanks for the help guys!
