I thought when the size of the barrier gets greater than the wavelength diffraction no longer occurs (or is a lot less noticeable). This is what I was referring to as cutoff, however maybe I was wrong.

Thank you for the proof. I will attempt to read past the first page when I have some more time on the weekend.
Also thanks Claude for your explanation. I can understand how the size of the aperture relative to the wavelength is important rather than the actual size. But then why is there such...
Hi,
I have a question about the phenomena of diffraction.
Diffraction is said to be the bending of waves as they pass through a gap or around an object in the path of the wave. Diffraction occurs if the wavelength is greater than the distance across the gap through which it is traveling, or...
