Hi there,

I need to model the scattering from structures near a ground seen as a PEC plane.  
I know that BEMPP only has functionality for free space Green’s functions and that half-space models are not currently supported (cf :  
[How can I define a MtE operator on a bounded plane?](https://bempp.discourse.group/t/how-can-i-define-a-mte-operator-on-a-bounded-plane/221), and :  
[Accounting for ground effects in acoustic radiation](https://bempp.discourse.group/t/accounting-for-ground-effects-in-acoustic-radiation/264)).

In my case, modelling the soil as a finite screen or implementing the method of images would be too computationally expensive.  
Does anyone know how I could implement this functionality in BEMPP, e.g. by using a half-space green function?  
Thanks in advance.
