Dear Users,
I am new to comsol. I have tried the example of a gold nanosphere in RF module. I have obtained directly the scattering cross section, extinction cross section and absorption cross section in comsol. Now my question is that, how to find the extinction efficiency, scattering efficiency and absorption efficiency?

Thanks in advance.

Best regards,
Cecil

How did you find the cross sections using comsol ? As far as I know, efficiency should be the ratio of corresponding cross section and area of the sphere.

Thanks !

Can you kindly tell me how did you get the scattering cross section directly?

What I would do would be choosing a line, extract the values from this line, plot the curve on excel (you ll get an exponential) and you will be able to get those values
