Units used for E,I,P, etc.
Hi! Thank you very much for this beautiful package. I am trying to use pyGDM to calculate the net force on an arbitrarily shaped particle in an optical tweezer. I need the absolute value, but I can not understand the units, pyGDM is returning, for instance, linear.farfield or linear.nearfield. Looking into the code, I don't see any constants used for the E->I conversion at all. Also, I cannot specify the total power of the incident field. Is a Watt assumed? Also, what is the best method to calculate it? I have calculated the MST from the farfields and nearfields, however I don't see consistent values. Thank you very much for the answers in advance!
