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.

As mentioned previously, abs^2 is power or intensity quantity, and since it is already normalized, you can label it as transmission/reflection of the specific mode. When we say S parameters, they are always associated with modes. In broad definition, plane wave, Gaussian beam and waveguide modes are all "modes".Â
