We refute a physical model, recently proposed by Gunn, Allison and Abbott(GAA) [arXiv:1402.2709v2], to utilize electromagnetic waves for eavesdroppingon the Kirchhoff-law-Johnson-noise (KLJN) secure key distribution. Their model,and its theoretical underpinnings, is found to be fundamentally flawed becausetheir assumption of electromagnetic waves violates not only the wave equationbut also the Second Law of Thermodynamics, the Principle of Detailed Balance,Boltzmann's Energy Equipartition Theorem, and Planck's formula by implyinginfinitely strong blackbody radiation. We deduce the correct mathematical modelof the GAA scheme, which is based on impedances at the quasi-static limit.Mathematical analysis and simulation results confirm our approach and provethat GAA's experimental interpretation is incorrect too.

Do electromagnetic waves exist in a short cable at low frequencies? What does physics say?
