Tech Note 2: Scalar Coils — Inductive Coupling Geometry Notes

Filed by Anti-Dave


Overview:

In scalar coil experiments, traditional electromagnetic rules often break down in unexpected ways. These notes are based on empirical bench work — not textbook theory — and are intended to inform Guild-level builders working with bifilar coils, capacitive tuning, and scalar resonant systems.


Key Observations:

1. Electromagnetic Cancellation ≠ Scalar Null

Two tightly wound bifilar spirals (conductors side-by-side) may appear electromagnetically inert due to near-total inductive cancellation — but this does not mean scalar potential is canceled.

  • EM cancellation = no field projected

  • Scalar activation = phase-tuned potential interaction

This distinction is essential for builders designing for scalar wave propagation rather than power transfer.


2. Inductive Coupling Behavior Is Nonlinear

Standard coupling formulas assume uniform inductance and spatial overlap. But with flattened bifilar coils, coupling becomes geometry-dependent:

  • Offset spirals lose coupling efficiency

  • Even minor misalignment (<3°) introduces unpredictable phase distortion

  • Best results occur with mirror-symmetry and variable capacitor tuning at the junction


3. Dielectric Medium Affects Field Shape

Substrate or mounting material influences field geometry:

  • Wood or cardboard yields more diffuse (natural-feeling) response

  • Acrylic or plastic = sharper resonance peaks but potential field confinement

  • Air gap between layers = useful for scalar bleedthrough experiments


Coil Construction Tip:

If you’re experimenting with inductive pickup from a scalar-bifilar coil, try this:

  • Place a single-loop flat spiral coil beneath the bifilar plate

  • Connect to a high-Z input scope or amp

  • Sweep frequencies in low MHz range while adjusting phasing capacitor

You may observe a “phantom signal” or non-Hertzian coupling artifact — especially near Schumann harmonics or biological window frequencies.


Closing Thought:

These geometries do not behave according to traditional textbook EM.
They behave more like acoustic instruments — responsive to resonance, symmetry, and intention.

“Sometimes the wire matters less than the silence between the turns.”
