A Delta-Resolution Framework for Mid-Range Wireless Power Transfer: Reinterpreting Radiation Loss, Range, and Experimental Constraints

Recent experimental advances in mid-range wireless power transfer (WPT), particularly those reported by Finnish research groups, demonstrate improved efficiency through radiation-suppression techniques such as phase-controlled current distributions and geometric symmetry. These results are typically interpreted within an energy-transport narrative, attributing performance limitations to radiative energy leakage. This work presents an alternative but fully Maxwell-consistent physical interpretation based on a delta-resolution framework. Wireless power transfer is described as the introduction of a controlled electromagnetic non-equilibrium (delta) by a primary system, which resolves locally either at an intended receiver or prematurely into environmental modes. Radiation loss is reinterpreted as premature delta resolution, structurally analogous to decoherence in open quantum systems. A resolution-rate model is introduced to formalize this interpretation, redefining efficiency and operational range in terms of competing resolution channels rather than transmitted energy. Range is shown to be constraint-limited rather than power-limited. The framework preserves all reported experimental observations while offering clearer causal explanations for radiation loss, efficiency collapse, and distance thresholds. The paper further proposes experimentally testable validation methods, including time-domain ringdown analysis, environmental sink modulation, and constraint-symmetry tests, enabling direct extraction of resolution rates. The framework provides actionable engineering guidance for extending effective WPT range and offers a unifying perspective across classical electromagnetism, radiation phenomena, and decoherence theory.
