- | Calculations in 2D are performed using the GSvit2D solver which is an almost unused extension of GSvit to 2D calculations. As this was very outdated, most of the algorithms had to be implemented, incuding near-to-far field calculation and various materials treatment including dispersive metal treatment via PLRC algorithm. | + | Calculations in 2D are performed using the GSvit2D solver which is an almost unused extension of GSvit to 2D calculations.

the same voxel spacing (5 nm), it is only from a different materials for calculation speed and simplicity. All the computational details were same as in the previous example. | the same voxel spacing (5 nm), it is only from a different materials for calculation speed and simplicity.
