USP Field Theory — Blood Resonance Compatibility (Complete Edition)

This document, authored by Sadegh Sepehri (October 2025), reinterprets blood-type compatibility through the USP Field Theory framework, replacing traditional antigen–antibody explanations with a resonance-driven Δf model. According to this approach, compatibility arises when the frequency deviation (Δf) between donor and recipient remains below a critical threshold (Δf < Δf₍crit₎), enabling constructive field coupling and stable biological coherence. The study integrates indirect biological and spectroscopic evidence — such as dielectric permittivity peaks (10⁶–10⁹ Hz) and optical/microwave absorption differences among blood types — and proposes measurable laboratory validation using terahertz spectroscopy and magnetic resonance force microscopy (MRFM). The work introduces the Δf Compatibility Map, outlines the Geometric Resonance Interpretation, and presents a unified glossary linking USP physics to biological behavior. This paper serves as both a theoretical model and an experimental roadmap for resonance-based biofield analysis.
