Primes

• Signal Decay and Fadeout
  • This pattern emerges wherever a quantity propagates, diffuses, or exerts influence across a system, and environmental or inherent factors attenuate that quantity predictably, a generality Friis (1946) captured for electromagnetic propagation in his canonical transmission formula relating received signal power to distance and aperture.

    This sourceCanonical electromagnetic-propagation result relating received signal power to transmitter power, antenna apertures, wavelength, and distance; mathematical archetype for environmental attenuation of a propagating quantity.

Domain-specific

• Friis transmission equation
  • Conceptual link-budget relation only; no surveillance, jamming, targeting, or deployable radio configuration is provided.

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
