Reply To: PML boundary conditions for scattering

[Rosmin_Elsa_Mohan]

 

Hi Amrita,

I would like to refer to the Mie scattering example , Mie scattering (FDTD) – Ansys Optics , the boundary conditions are PML on all sides. Can we use PML if more spherical structures extend uniformly in all directions, that is more particles within the scattering/absorption analysis regions ?  As you mentioned if its non periodic structure , we can use PML – does this hold true here? 

If PML BC are used on x,y,z directions and if the ‘extend through PML’ is checked – can we assume the strucure(s) are extending through the PML boundaries? 
Appreciate the advice.
