The Wave Machine Calculated Its Own Gradient
A nonlinear multipath experiment extracted optimization sensitivities from the hardware itself, without a digital twin.
Summary
A nonlinear multipath experiment extracted optimization sensitivities from the hardware itself, without a digital twin.
The platform uses incommensurate coaxial cables, T-junctions and one diode-loaded nonlinear cavity to create repeated scattering paths. A matched adjoint excitation lets measurements recover the gradient needed to optimize the system even though superposition no longer holds globally. The experiment turns multipath complexity and a localized nonlinearity into resources for control, pointing toward adaptive communications, imaging and analog intelligence in partially unknown environments rather than demonstrating those applications directly.
Why it matters
