" The radiation toward an elevation angle of 5 degrees shown in the surface
wave plot continues in essentially a straight line, to reach the
ionosphere."
I'm still puzzled by these statements.
What is NEC calculating when one selects the surface field? I am under the
impression that it finds the

I will preface my question by saying that I haven't worked through a problem
like this in 20 years, so it's quite possible that I'm forgetting some obvious
details.
I'm puzzled by how this surface wave can reach the ionosphere. I believe you
are saying that the standard MoM solution ignores the
