Sub-Space Communication System (SSC) – Scalar-Tensor Metric-Engineered Transceiver Stack

Abstract

This project presents the system architecture, mathematical framework, and bench-level implementation for a Sub-Space Communication System (SSC)—a high-voltage, phase-anchored transceiver stack designed to establish low-latency, noise-resilient communications. Departing from conventional transverse electromagnetic ($\text{TEM}$) radio wave propagation, the SSC framework investigates localized field coupling across a scalar-tensor boundary, establishing an engineered metric corridor that reduces the effective geometric path length between nodes without violating local Lorentz invariance ($v = c$).
The core physical engine utilizes an asymmetric high-permittivity ferroelectric cavity ($\text{BaTiO}_3$) driven by a wide-bandgap Silicon Carbide (SiC) / Gallium Nitride (GaN) high-voltage switching bridge. This arrangement translates digital baseband signals into extreme localized electric field gradients ($\Phi$). Nonlinear field stability and soliton-like self-trapping are maintained through a cubic restoring potential ($\lambda\Phi^3$), preventing runaway growth or rapid thermal dissipation of the boundary state.
At the digital layer, a Software Defined Radio (SDR) front-end executes a Generalized Orthogonal Frequency Division Multiplexing (G-OFDM) modulation scheme paired with Raptor fountain coding. By utilizing a frequency-domain filter matrix ($G$), out-of-band spectral leakage is suppressed while distributing signal phase information across a multidimensional subcarrier grid. Coupled with picosecond-level precision clocking (OCXO/GPSDO), the system achieves robust non-radiative field coupling resistant to environmental phase distortion and localized narrowband interference.
