Driven Curvature Effects in High Q Electromagnetic Cavities

This document presents an early formal treatment of a prediction emerging from the LaMarche Linear Factor (LLF) framework. The work explores the possibility that highly coherent electromagnetic systems may introduce small spacetime responses when energy density, phase coherence, and oscillation frequency remain strongly confined within high-Q resonant cavities. The paper develops a minimal covariant formulation introducing a coherence-driven spacetime loading parameter that depends on electromagnetic frequency, coherence time, and local energy density. Within this formulation, a scalar deformation mode represents the lowest-order spacetime response to coherent temporal loading. From this framework, a testable laboratory prediction emerges: high-Q resonant cavities may exhibit a small fractional frequency shift that scales with the square of the electromagnetic confinement parameter (PQ/V). This scaling differs from conventional optical Kerr nonlinearities and provides a potential experimental discriminant. The purpose of this manuscript is not to present a complete gravitational theory, but to isolate a single falsifiable prediction derived from the broader LLF framework. Precision optical and microwave resonator systems are identified as potential experimental platforms capable of probing the predicted effect. This document is released as Working Preprint Version 0.1 to establish a timestamp for the framework and to invite technical feedback from the scientific community. Portions of the formal derivation and parameter constraints remain under active development and may be expanded or modified in future revisions.
