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.

Please extract the imported source data and recalculate its power. As mentioned previously, EME assumes mode power of 1Watt. Maybe your imported fields have larger than 1 v/m electric fields. However the solver assumes it is 1v/m so yo increase its amoplitude to 1e^11. Usually it is on the order of 1e7. This might be the reason 1e^4.

You can either nromalize the import fields, or normalize the result. eg, S11=S110*Mode_power/Calculated_mode_power.
