Hi,
I've been simulating a lot in 2D for the purpose of imaging. However, my imaging algorithm assumes a 3D signal propagation, i.e. based on the exponential function, while numerical solutions of 2D propagation use Hankel functions, thus causing a different distribution and dropoff of the signal energy over range. How is that handled in gprmax?

Best,
Dominik

Hi Dominik,

gprMax simulates full wave propagation. There will be different geometric spreading (and hence amplitude delay) between 2D (circular wavefronts) and 3D (spherical wavefronts) which you will see if you compare 2D and 3D simulations in gprMax.

Kind regards,
Craig
