Your last two statements are false. Please stop trying
to tell others what I mean when it is obvious that you
don't know what I mean.

This is getting stranger by the day.

Why can't you and I just have a reasonable technical
discussion? Sooner or later, the readers who care at
all about the truth are going to see through your
attempts to falsify what I have said.

Since you obviously have not understood what I said in
the past I guess I need to simplify it for you so here goes:

Let A be the forward traveling current.

Let B be the rearward traveling current.

Let C be the part of the forward traveling current
that flows through the load.

Let D be the part of the forward traveling current
that doesn't flow through the load and becomes B
after being reflected.

A = C + D The total forward current is divided
into two components, one accepted by the load and
one rejected by the load.

The following is phasor addition

Total Current = A + B = (C + D) + B = C + (D + B)

(D + B) is the pure standing wave current component,
a part of the forward current equal to the reflected
current.

The total current is indeed the phasor sum of the
forward and reflected current.

The total current is also the sum of the load current
plus the pure standing wave current. The pure standing
wave current envelope is sinusoidal.
