Experiment 05 · Wave Bench

Side-by-side. All five.
And the Tri-Bhaga continuum.

The bench runs the same FDTD solver against multiple geometries (or the same geometry at multiple Tri-Bhaga ratios) under an identical broadband impulse, and overlays the spectra and Q values so the comparison is read off a single chart, not three.

· everyday-language one-paragraph version
Wave Solver, but running on a hundred different setups at once. Sweeping through many sizes and recipes so you can see the pattern, not just one snapshot. This is the chart no real engineer ever skips before sending a design to a workshop.
WHAT YOU ARE LOOKING AT
The same physics engine as Wave Solver, but sweeping a parameter automatically — geometry, Tri-Bhaga ratio, frequency — so you see the trend across many configurations instead of one snapshot.
WHY THIS MATTERS FOR QUANTUM
One simulation gives one number. A sweep gives you the response curve — where the resonance peaks sit, how sharp they are, how tolerant the design is to manufacturing error. No engineer commits to fabrication without this kind of plot first.
WHAT TO WATCH
A sharp single peak means the design is selective but intolerant. A broad shoulder means tolerant but blunt. The Compare-all overlay shows where the Dhara sits relative to the standard shapes across the whole sweep.

Bench parameters

5 geometries · 12000 FDTD steps each · broadband Gaussian impulse · σ = 50 µs · same source position, same boundary conditions, same PML width. Expect roughly 40 – 120 s depending on host CPU.

What this proves

Under identical excitation, each geometry exposes its own dominant mode. The sphere shows the cleanest single peak (high Q, narrow band). The cube shows multiple closely-spaced peaks (mode crowding). The Dhara composite shows the longest decay tail when the directional channel is closed, and a clear outflow signature when open. Pareto position is read from the shape of these spectra, not from a list.
