The module currently features models of antennas similar to commercial antennas:
|
|
|
|
* Geophysical Survey Systems, Inc. (GSSI) 1.5 GHz (Model 5100) antenna (http://www.geophysical.com)
|
|
* MALA Geoscience 1.2 GHz antenna (http://www.malags.com/)
|
|
|
|
A description of how the models were created can be found at http://dx.doi.org/10.1190/1.3548506.
|
|
|
|
The antenna models can be accessed from within a block of Python code in your simulation. The models must be used with cubic spatial resolutions of either 1mm (default) or 2mm. For example, to use Python to include an antenna model similar to a GSSI 1.5 GHz antenna at a location 0.125m, 0.094m, 0.100m (x,y,z):
