Custom transmitter and receiver

[Delfina RJ]

Hi! I'm working in an experimental project on electromagnetic scattering and gprMax turned to be really useful, thanks!. However, i'm having trouble in uploading a custom antenna to gprMax, and using it as a transmitter and a receiver. Could you help me?

Best regards,

Delfina

Hi Delfina,

Are you talking about 1) a complete antenna geometry? or 2) just a custom waveform? 

For 1) you would have to build the antenna using gprMax geometry primitives (#box, #plate, #edge etc...) or you could import a geometry using the #geometry_objects_read command if you can get it in a suitable format, see docs - https://docs.gprmax.com/en/latest/input.html#geometry-objects-read

For 2) you can import a custom waveform shape from a file and use it with a simple source such as a Hertzian dipole, again see docs - https://docs.gprmax.com/en/latest/input.html#excitation-file and https://docs.gprmax.com/en/latest/input.html#hertzian-dipole

Kind regards,

Craig
