If you're interested in the application that got send to the European Court for Human Rights, you can read it here directly: https://einarflydal.com/wp-content/uploads/2023/08/20230801-Info-Complaint-on-electricity-meters-before-the-ECtHR.pdf It explains in short what the issue is all about, though the focus in on Smart Meters, there is no difference when it comes to other wireless devices that emit pulsed microwave and millimeter wave radition.

Paper day! together with some colleagues we wrote an article about the #electromagnetic boundary conditions between two media in relative motion.

As it turns out, we need to use the wrong boundary conditions to get the correct results!

AAAS: "Satellites leak radio waves." SpaceX is injecting more + more internet-beaming Starlink satellies into orbit. This is polluting parts of the radio spectrum, risking interference with ground-based radio telescopes. "Using the Low Frequency Array (LOFAR) in the Netherlands, researchers detected “unintended electromagnetic radiation” from the onboard electronics of 47 out of 68 observed Starlink satellites, unrelated to internet signals or other downlinks, the research team reported last week in Astronomy & Astrophysics." Previously radio astronomers raised an alarm that Starlink downlinks could interfere with protected radio bands used to identify organic molecules in space. "With more than 2000 Starlinks in orbit and many more planned, the authors urged satellite operators and regulators to consider these emissions in future designs." So, not just visual pollution for all of us as stargazers, but the radio portions of the the electromagnetic spectrum are impacted as significantly as the visual parts of the electromagnetic spectrum we are all dependent on. Another failure of the free market, requiring national + international regulation to keep our skies clear. After all, we are all on the spectrum.   #starlink    #electromagnetic    #spacepolicy

QST I'm developing an #opensource curriculum for @thenrao #hamradio project focused on defending and keeping parts of the #electromagnetic #spectrum open for #citizenscience and public use. Ideas? gogo!

This seems like a promising approach: a bit of physics informed and has flavor of DDA.

'a Graph Neural Networks (GNN) architecture which learns to model #electromagnetic scattering, can be applied to metasurfaces of arbitrary sizes. Most importantly, it takes into account the coupling between scatterers. Using this approach, near-fields of #metasurfaces with dimensions spanning hundreds of times the wavelength can be obtained in seconds.' #photonics #GNN #MachineLearing

#Airgapped computers can have sensitive data intercepted via the use of planted #malware and a #receiver (such as a laptop or smartphone) that gets the data through #electromagnetic radiation. Pretty wild! #Countermeasures have their own drawbacks, though curiously the method of interception doesn't seem to work that well with a laptop.
