文档介绍：The variation of the PML condition will affect the extinction cross section
In the model of Mie Scattering Plasmonics(“Mie Scattering of Plasmonic Nanoparticle and Radar Cross-putations”,Model ID: 3459, Comsol ), the different PML size will lead to different extinction cross section.
The cross sections of the calculated 3D structures are in figure 1. The blue rings are PML layers, gold balls are gold nanoparticles, the white parts are air. The black circles are integration spheres. The inner radii of PML are A: 210nm, B: 250nm, C: 300nm. The setting and other conditions are the same with the original modle.
However the calculated extinction cross sections as a function of wavelength are not identical as showed in figure 2. This calculated result is against the physics.
