Electromagnetic Black hole phenomena

AI Thread Summary
The discussion centers on the concept of electromagnetic "black holes" that can concentrate light, as highlighted in recent articles. Participants express skepticism about the implications of this discovery, particularly regarding its potential violation of the second law of thermodynamics. There is a debate about whether the phenomenon can effectively manipulate light in a manner similar to gravitational black holes, with concerns about frequency sensitivity and the validity of the reporting. Some believe the claims may be exaggerated or sensationalized. Overall, the conversation reflects a mix of intrigue and caution regarding the scientific claims made about this phenomenon.

Electromagnetic "Black hole" phenomena

Just read the article and you will understand the title. I'm not sure where I should put this so if you want to move it go ahead. But this shows great potential in my eyes. A brilliant discovery if made applicable.

Interesting.
But if that thing can indeed concentrate completely diffuse light it would violate the second law of thermodynamics.

That's what I was thinking. The science writer is horribly obtuse, so it's difficult to sort out what what the ideal is all about.

I think the idea here is that light will take spiraling paths to where it is intended to go, as the spiraling paths of light do near an event horizon. This would be a novel idea to me.

Now I would ask, if my guess is right, "isn't it frequency sensitive so that only narrow bands will follow decending paths and the rest scattered." I think this is sensational reporting. My initial take is that this is hyperbole.

I think that it only works for microwaves. But they say the same principle can apply to optical light.

How exactly does it violate the 2nd law?
 
This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...
Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'
Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
