#scattering — Public Fediverse posts

@mdhughes i really like "scattering" for #decentralization .
I've been using #decent9n but I think #scattering and #scattered (for #decentralized) might be my new alternatives. Will contemplate. 🤔😊

Scattering VS Extinction
In #Optics, the concepts of scattering and extinction are closely related. So closely related that many people tend to confuse them.
Imagine to illuminate a small object with a beam of light. If the object is small the scattered field will be essentially a spherical wave, and the total field will be the incident one plus the scattered field.
If we were able to measure directly the field (as we can do in the microwave regime) we could happily stop here, but in optics we can only measure intensities, and the intensity is defined as the time average of the modulus of the Pointing vector. In most cases of interest, the modulus of the Poynting vector is proportional to the modulus squared of the electric field (which explains why we often that a shortcut and just talk about |E|²).
So the quantity we measure is proportional to |Eᵢₙ +Eₛ|², which is the sum of the Poynting vector of the incident field, the Poynting vector of the scattered field, plus the cross terms. These cross terms are what we usually call "extinction" and are the result of the interference between the incident and scattering fields(and the reason why you get a "shadow" behind the scatterer).

I haven't made a single scientific animation in months. I just don't have the mental space right now.
But I am preparing a series of lectures on scattering for the Plasmonica 2026 School (https://www.plasmonica.it/2026school/), and it feels like a good excuse to make a few new ones.

This one shows a simple finite element simulation of a pulse scattering on a small dielectric obstacle.

I accidentally found this effect while brooming one day, is it scattering the light?
Uploading the vid so you can see how the rings of light change depending on the position of the reflecting metal.

#Blender #GodotEngine #Scattering

Hey,
In :blender: one can use geo-nodes to scatter stuff.

The problem is to apply the modifier, i.e. on export, all those scattered instances turn into geometry - i.e. they are not shared/linked data.

On the :godot: side, I am hacking a plugin to try detect any clue that can help me spot when a scatter is coming in - i.e. I want to capture the transforms of each instance and the mesh data once. So I can make a multimesh.

any ideas?

@afreytes I found some old code and spruced-it up a bit (for 4.3). It scatters stuff onto the triangles of faces of target meshes.

It's a tool, but with little effort it will work in-game too.

Play around with it and ama.

After accounting for all variables, we're seeing something funny when subtracting backgrounds that put question marks on fundamental background subtraction practices in scattering.
So I wrote a little bit about it:

"Here, we realize a Fermi gas featuring both strong, tunable contact interactions and #photon-mediated, spatially structured long-range interactions in a transversely driven high-finesse #optical cavity. Above a critical long-range interaction strength, density #wave order is stabilized in the system, which we identify via its #superradiant light-#scattering properties."

Any pointers to good sources for non- spherical electron density distributions? Even a first order correction with S + P orbitals?

Not to be greedy, but any sources for MO for isolated amino acids or short peptides?

We had a terrific start yesterday for the #DPG spring meeting with Yimeng Wang's talk (on #EntanglementGeneration during #Scattering) and the two posters of Jonas Fischer and Josias Langbehn. #SAMOP23 👏

"We used spectrophotometry, electron microscopy, and optical modelling to explain the mechanisms producing bright white tail feather tips of the Eurasian woodcock Scolopax rusticola. Their diffuse reflectance was approximately 30% higher than any previously measured feather. This intense reflectance is the result of incoherent light scattering from a disordered nanostructure composed of keratin and air within the barb rami"
