Sorry, I'm not sure what result you mean. You can't change the
reflecting angle -- the angle of reflection is always equal to the angle
of incidence. And the intrinsic impedance of a medium doesn't change
when a wave strikes it, reflects off it, or propagates through it.

I wanted to mean to choose the incident angle for possible anothers
calculations, Sorry I get confussed with translated meaning of angle
in = "Intrinsec Z = xxx at ANGLE of xxx deg, I understood as
incidence angle instead of phase angle, here we can not acostumed to
write in that form and I translated bad the meaning.

Intrinsic impedance is a complex number unless the medium is lossless
like free space, so the impedance of ground is complex. A complex number
can be expressed in rectangular form (real and imaginary) or polar form
(magnitude and angle). EZNEC shows the impedance in polar form which
includes an angle. The angle is part of the impedance and has nothing to
do with any field. Many scientific calculators can convert the polar
number into rectangular form if you prefer.

Today I posted another EZ-NEC question about a simulation of liquid
antenna based in yours, but I did on earlier thread post point, have
you see it?

Yes, I posted a response.
