Structured Resonant Coupling (SRC): A Testable Framework for Temporally Structured Field–Medium Interaction

Structured Resonant Coupling (SRC) defines a testable framework for investigating how temporally structured electromagnetic excitation interacts with reactive systems exhibiting relaxation dynamics. The framework examines whether coordinated time-domain structuring of excitation signals, combined with passive phase-selective feedback, leads to measurable differences in phase stability, impedance behavior, and transient response. SRC operates entirely within classical electromagnetic and circuit theory and introduces no new physical principles. Its contribution lies in formalizing temporal excitation architecture as an experimentally controllable design variable. A comparative experimental architecture is defined to enable controlled evaluation between stationary and temporally structured excitation under matched conditions. Explicit falsification criteria are provided. The document is intended to support independent replication and critical evaluation. A complementary technical document (Level 2) provides detailed implementation architecture and measurement methodology.
