FAQ CSAMT / CSEM
======================

Dipole Orientation
---------------------

In almost all cases you need two dipoles perpendicular to each other.

In case of **CSEM** and *near field* data you want to control the wire path (dipole cable). |br|
The L-shape layout comes close to this requirement.

Assuming following electrode positions


U North |br|
V East |br|
W South & East

we get following transmission angles
