Negative Damping, Coherence Activation, and Impedance-Matched Transmission in a Scalar Field Model

This work develops the dynamical and transmission-level consequences of a scalar coherence field operating near a negative-damping threshold. Building on prior derivations of coherence-mediated stress and solitonic structure, the paper analyzes the conditions under which coherent order can be sustained, transmitted, and stabilized in noisy environments.

A signal-theoretic framework is introduced to address impedance mismatch between high-coherence sources and low-coherence loads, motivating a passive resonator and low-power broadcasting regime. All claims are formulated in a falsifiable manner, with explicit failure modes, null controls, and operational measurement protocols intended to support independent experimental testing.
