GENERAL DESCRIPTION OF
                    ENERGY TRANSFER   Consider energy, flowing straight and level down
                    the proximity of a transmission line. The energy does not know the width of the
                    channel through which it is passing. If the energy reaches a point where the dielectric
                    changes (but not the geometry), some of it will continue on and some of it will
                    reflect. If the energy reaches a change in the width of the transmission line some
                    will reflect and some will continue as well. The energy current will not know whether:
                

Energy current does not have
                    directional inertia, so that (a) is equivalent to (b). Energy current does
                    have an aspect ratio. If the aspect ratio is forced to change, some of the flowing
                    energy will reflect in order to assure that its total aspect ratio remains
                    constant. Crudely, the aspect ratio is similar to the ratio of E to H, or the same
                    as the ratio of
                    to µ.
                    The aspect ratio of energy current is much like the aspect ratio of space. While
                    the aspect ratio of space can change, it fundamental velocity
                    cannot really change. This parameter becomes
                    merely our way of conceptualizing time delay when energy resides in a region of
                    space.  
                    
                    A /B = Aspect Ratio 

Aspect ratio defines the shape
                    of energy entering a given region of space, but not its amplitude. Velocity or length
                    define the time during which the properly shaped energy can be accommodated by a
                    region of space. Aspect ratio is really a definition of the relative compatibility
                    of adjacent regions of space. Does flowing energy current largely travel unimpeded
                    through an interface, or does it largely reflect at the interface? Space has quiet
                    zones through which energy glides virtually unreflected. There are also noisy zones
                    where energy current becomes incoherent, bounces about and splits apart. Noisy zones
                    in space have either rapidly changing geometry or rapidly changing impedance ().
