5 kW inductive link at 1.00 m: Maxwell 3D specification
manuscript in preparation
Geometry, eddy-current formulation, energy extraction of M, k and η at the optimal load. Every number is simulated until G0.

No invented papers or DOIs. What exists today is the site corpus and a manuscript in preparation.
Full model and manufacturing-package PDFs leave only under NDA, via the data room.
Method note (site corpus)
Cross-checked FEM method: Maxwell 3D / COMSOL AC/DC
published on this site
Boundary A × n = 0, mesh to δ/3, M and R_ac convergence, loss and force post-processing. No measurement above 1 kW.

}Collaboration — what we give and ask
Three open topics. Write with an affiliation. This site does not invent academic titles.
We give: Maxwell model, COMSOL cross-check, 5 kW manufacturing package, tank specification (under NDA).
We ask: lab time, Litz/Q test, PD on a kV-class tank, or ICNIRP mapping on a fenced site.
Litz and Q
Proximity n·d_s⁴; target √(Q1 Q2) ≥ 560 after G1.
kV tank and PD
Gate G2: 25 kW, one module, partial-discharge qualification.
ICNIRP
Simulated contours 3.3 m (100 kW) and 6.3 m (1 MW). No site measurement yet.
