Simulating the Interference Pattern of Fraunhofer Diffraction

Click For Summary
SUMMARY

The discussion centers on simulating the interference pattern of Fraunhofer diffraction, specifically addressing the impact of slit dimensions on the resulting pattern. Participants highlight the importance of ensuring that the slit height is significantly larger than the slit width to avoid fringing effects in both dimensions. Additionally, they emphasize the necessity of verifying units to confirm that the simulation is conducted in the far field, where Fraunhofer approximations apply. These factors are critical for accurate modeling of diffraction patterns.

My first guess is that maybe the slit height was not specified to be significantly larger than the slit width giving fringing effects in both dimensions. Is this the case?

Also you may want to recheck your units to be sure you are indeed in the far field where the Fraunhofer approximations are valid.
