Calculation record

Independent full spatial Fourier checks of scalar wave quartets.

Research context

  • Resonant scalar wave quartets

    Four positive-frequency spatial waves permit reciprocal scalar norm transfer; the exact coherent contraction and its sharp bound depend on complete polarization vectors, with a right-angle cancellation restricted to one polarization per chiral band.
