... energy in the region of integration is just the flux of energy through the boundary of the region represented by the surface integral on the left . Thus the vector ( Ex H ) Απ apparently gives the amount of energy flowing through unit ...

... energy flux is consistent with the ideas of the special theory of relativity . ( According to the special theory of relativity , energy has inertia and thus energy flux is associated with momentum . ) Considering a plane wave we have ...

... energy flux and energy per unit length can be gone through in an exactly similar manner for the TE modes leading to equations ( 27 ) , ( 28 ) and ( 29 ) where only E is replaced by B. Equation ( 30 ) is thus generally true . It is of ...
