We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Giovanni,

Can I say that the maximum value reported of 124 is actually the field enhancement E/E0? 

Yes, I would say that 124 is the field enhancement.

In linear simulation, we do not actually need to change the amplitude of the source. The field enhancement will not depend on the value of the amplitude. As you mentioned, it is going to remain 124 even when you reduce the amplitude by 0.5. The absolute power will depend upon the amplitude of the source. But, if you know the power for any given amplitude, you can easily determine the power for other amplitudes by simple multiplication. So, in any case (linear simulation), I would recommend you to keep the source amplitude 1, and then you can use the field distribution to calculate the field enhancement.
