A strange piece of #RF #junk
There is a clear WR-90 #waveguide going into that shielded end of the thing.

Hah. Apparently I'm the #waveguide person these days.

"Hey I have these two large waveguide dummy loads, do you want them?"
And here they are.
#microwaves #surplus #junk

- details on image / tomo reconstruction
- inhomogenous generalisation of contrast transfer function #CTF
- non-linear #Tikhonov #regularisation
- empty beam problem in #holography, filtering by an #xray #waveguide
- human lung tissue (alveolar capillary dysplasia)
