I've published a technical report on Zenodo detailing physical-layer side-channel leakage observed during the processing of a raw satellite signal capture (satellite_signal.bin).
​DOI: https://doi.org/10.5281/zenodo.21472996 ​SHA-256: ad5ab850cbdc9eca534e82bd78e9ac7804ed9213fd1d8df26fbf4991df6b005d
​Methodology: ISO/IEC 17825 CPA, 1st/2nd-Order TVLA, and Jitter Cross-Correlation.
​Key Findings: ​1st-Order TVLA Leakage: Welch's t-test yielded a risk score of 13.0328, well above the standard statistical significance threshold (\vert{}t\vert{} > 4.5), confirming direct data-dependent leakage during processing.
​S-Box Capacitive Leakage: Identified at the execution cycle with a t-score of 7.6701, indicating power/capacitive fluctuations correlated with substitution box operations.
​The report contains the verification metrics and signal processing details. I'm looking for feedback from anyone working on physical layer security, RF side-channels, or power trace analysis regarding jitter compensation techniques for long captures.

Mechanical mating does not guarantee electrical performance. A precision adapter can protect an expensive instrument port, so interface condition and traceable S-parameters matter.

For a practical check, I would record interface compatibility, connector gauge, torque, measured S-parameters. Mechanical fit or a printed label alone does not describe the complete measurement path

I am interested in how other benches handle this. Do you treat adapters as consumables or calibrated bench assets?

Hi guys,

Just came across a paper in TMTT Early Access. (https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11610586)

Have no idea why this kind of paper can be accepted.

What do you think?

Hi everyone,

I'm trying to learn how to optimize my high speed PCBs (think <100ps edges), especially focusing on SMA transitions, vias and power combiners. I've got a brick wall trying to hand tune stuff by trial and error and would like to move to simulation based optimisation.

I did some research into free/cheap FEA simulators and it seems that openEMS is the most recommended one. Unfortunately all the materials I found do a terrible job at explaining how to use it. Does anyone have any good source to recommend?
