Overview

A scalar EM wave, if Bearden's framework is accepted, carries information in the scalar potential component — not in the classical magnetic vector potential. Conventional antennas and receivers are insensitive to it. The scalar-to-vector demodulator uses a fast-switching nonlinear element (transistor or tunnel diode) that samples the potential asymmetrically, producing a transverse EM output proportional to the incoming scalar signal. This is analogous to the detection mechanism Bearden attributed to Soviet scalar weapon detection in the 1980s. The device uses a biased Josephson-like junction (approximated at room temperature with a resonant tunnel diode circuit), a sampling oscilloscope front end, and a DSP demodulation stage. This plan is paired with the Scalar Interferometer and Longitudinal Transmitter as a complete experimental system.

Intended Research Use

Scalar potential demodulation, longitudinal-to-transverse conversion experiments, Bearden scalar EM detection framework validation.
