In this case both 
and 
become real numbers.

From (6.61), we can see that, in medium 1 we have a traveling wave component with amplitude TEio and a standing wave component with amplitude 2JEio.
The location of the maximum and the minimum of the electric and magnetic field components in the medium 1from the interface can be found as follows.
The electric field in medium 1 can be written as
