Myself, Achyut Maity from Ben Gurion University, Israel. I am beginner in comsol simulations. Recently I am trying to calculate the scattering and extinction cross-section from an Au sperical particle sitting over a Si slab to mimic the dark field scattering spectrum. The modelled simulation is attached here. Her I have tried to calculate the scattering extingtion cross section of the Au particle in the upper portion of the modelling, i.e in the air domain. Here the light is incident in the particle from the positive z to negetive direction. Although the simulation is running, I can not obtain the desired spectrum. Instead of I am getting some noise like response. I know very well that such request definitely hamper your busy and tight work schedule, but considering the academic prospect of an young student I hope to get your positive response on this aspect.
thanks in advance
