hey guys, i was looking at this site: http://www.turnpoint.net/wireless/cantennahowto.html
and it explains how to build a waveguide out of a tin can. further down it has an automatic calculator and it shows the cutoff frequencies for te modes and tm modes... they are quite different... so how would one change the mode of propagation? or does the mode of propagation change itself based on the standing waves inside it?
thanks guys!
