Hey Shameemkabir, thanks for spending the time to view my project.
For my design, my objective is just to evaluate the difference between 1 source and 2 sources being place side by side. I wanted to see if the emission will be doubled as expected. But right now, for the 2-sources case, the results I've obtained are calculated from individual source separately instead.
The source is merely just a voltage source wired to a resistor. And I've placed near-field probes inside and outside of the box to measure the difference between the two. I tried to make the whole design as simple as possible. Please advise me if anything need to change.
Once again, thanks! Really appreciate your help =)
