**Towards a unified deterministic theory of fields and particles**

A deterministic model of a unified field and particle theory is developed from Einsteins vacuum gravitational equations, Ricci tensor **R**_{LM} = 0, in a higher dimensional space. It is postulated that the equations support soliton-type solutions (metrons) which reproduce all the basic field equations of quantum field theory. The structure of the solutions (a coupled wave-mode/wave-guide system) is illustrated for a simplified scalar Lagrangian. Bell's theorem on the non-existence of hidden-variable models of quantum phenomena is circumvented through the time-reversal symmetry of all interactions on microphysical scales. Although only the basic strucure of the metron model is presented in this first four-part paper, it is shown that all relevant physical particle properties and constants (electric charge, mass, gravitational constant, fine structure constant, the coupling constants and symmetries of the Standard Model, etc.) can be derived from the properties of the metron solutions.
