This technical note proposes a compact adaptive receiver architecture for directed laser wireless power transmission (WPT). The concept focuses on short-to-medium range power beaming for small mobile or remote systems such as drones, rovers, sensors, or isolated equipment. Unlike a classical concentrator that focuses incoming light into one small photovoltaic target, the proposed receiver distributes incident laser energy across an inner conical photovoltaic or semi-absorbing surface. This distributed inner-surface absorption is intended to reduce hotspot formation, improve thermal handling, and increase tolerance to beam divergence and pointing error. The document develops a single-cone baseline geometry, a dual-cone or switchable receiver strategy for adapting to different distance regimes, and a Fresnel-aware treatment of glancing-angle reflection inside the cone. It also addresses photovoltaic electrical mismatch by recommending parallel ring outputs, bypass protection, or independent maximum power point tracking (MPPT) for unevenly illuminated receiver zones. The work includes practical design equations for beam divergence, capture margin, system efficiency, absorbed power density, and ring-level electrical aggregation. It also defines predeclared falsification thresholds for low-power bench testing, including misalignment tolerance, hotspot reduction, Fresnel-aware absorption improvement, ring-zone tracking response, and electrical mismatch recovery. Within USP Field Theory, the laser is interpreted as a coherent Δf propagation corridor, while the conical receiver functions as a distributed Δf-coupling cavity. The USP interpretation is presented as an applied mechanism layer compatible with mainstream optical and photovoltaic engineering constraints. The note does not claim lossless power transfer or a completed high-power device; it provides a concept, engineering guardrails, and a validation pathway for future experimental or simulation-based work.
