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 wa

"The radiated field of a vertical monopole present on the surface of lossy earth decays at greater than a 1/R rate. But, for example, the field shown at a horizontal distance of 0.1 km in my surface

Thanks for the link. I'm still wondering about NEC and its surface analysis. I will have to find a more complete explanation of what it does. As I said before, it sounded to me like all of the radiat

" 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 i
