The Pyramid Antenna Hypothesis: A Speculative Model of Signal and Energy Coupling in Giant Dielectric Stone Structures

This paper proposes a speculative but physically framed hypothesis that large pyramidal stone structures, especially the Great Pyramid of Giza, may exhibit antenna-like electromagnetic behaviors under certain natural electromagnetic conditions. The paper does not claim that the pyramid has been archaeologically proven to be a power generator, communication device, or engineered electrical machine. Instead, it develops a testable model based on four components: giant dielectric stone geometry, possible weak geoelectric coupling, localized metallic elements, and natural VLF/LF electromagnetic background generated largely by global lightning activity. The paper first reviews the principle of helical antennas, including electrical length compression, inductive loading, and slow-wave effects. It then extends these concepts to a hypothetical large-scale spiral or distributed coupling structure. The model further considers the pyramid as a non-uniform dielectric resonator made of limestone, granite, mortar, internal cavities, and surrounding ground conditions. A cautious distinction is made between established evidence, engineering analogy, speculative inference, and experimentally testable predictions. This work is intended as a hypothesis paper and conceptual research proposal. It invites further numerical simulation, scaled physical modeling, electromagnetic field measurement, material conductivity testing, and geoelectric correlation studies. A Chinese companion version is included.
