LINES OF ELECTRIC FORCE 



LINES OF MAGNETIC FORCE 



Fig. 1— Approximate configuration of lines of electric and magnetic force in a 

 typical wave guide. Small solid circles represent lines of force directed away from 

 observer. Propagation is assumed to be directed to the right and awa> from the 

 observer.
