Triple-Chamber Vacuum Communication System — Theoretical Framework

The triple-chamber vacuum communication system is a theoretical electromagnetic resonance architecture constructed around two core geometries: (1) a concentric vacuum-core cylindrical system and (2) a vertically stacked thermal-gradient chamber system. Both structures use controlled refractive-index gradients, multi-coil magnetic excitation, and layered thermal regions to generate wide-band electromagnetic resonance within a confined cylindrical volume. This preprint outlines the geometric foundation, resonance physics, thermal–electromagnetic coupling, parametric modulation, and harmonic mode behaviour across a frequency range spanning from tens of MHz into multi-GHz. The model proposes potential use cases in broadband communication, directional emission, and high-Q cavity applications
