Hello,

Does somebody have experience with ANSOF (www.antennasoftware.com.ar),
especially with planar circuits? Is this a NEC based package?

They say you can use a flat strip as basic element (like in the
"planar" commercial SW packages), though they speak of wire segments
in most other documents on their site. They also mention that you can
simulate wire segments in dielectric or magnetic media. This looks
nice for the relative low price.

their description doesn't mention NEC:

"The computer code is based on an Electric Field Integral Equation
(EFIE) expressed in the frequency domain. The current distribution on
metallic structures is computed by solving the EFIE using a full-wave
Method of Moments (MoM) formulation with conformal geometry
decomposition. This means that geometry details are modeled by using
conformal segments, which exactly follow the contour of the structure,
instead of the typical approximation with straight wire segments. "

lots of nice words, and plenty of pretty pictures on their site... but
i wonder how well verified it is.

Something about the whole site seems to ring alarm bells with me, right
from the similarity of the name to Ansoft to the Western Union payment
option!!
