The Transverse Electromagnetic Wave. A TEM Step.

 

 

 

Traditionally. when a TEM step (i.e. logic transition from low to high) ( Figures 3, 4, 5 from Electromagnetism 1 ) travels through a vacuum from left to right, guided by two conductors (the signal line and the 0v line), there are four factors which make up the wave;

- electric current in the conductors i
- magnetic field, or flux, surrounding the conductors B
- electric charge on the surface of the conductors +q , -q
- electric field, or flux, in the vacuum terminating on the charge (Figure 2)
