HOW IT WORKS

A structured workflow for inverse RF/EM design.

01

Post target

Companies describe what they want — frequency range, S-parameter masks, gain, size, substrate, fabrication rules — using component-aware templates. Admin reviews the brief before publication.

Solvers compete

Verified solvers worldwide work the problem using their preferred tools (HFSS, CST, ADS, OpenEMS, MATLAB, Python). They can apply manual design, parametric sweeps, surrogate models, Bayesian optimization, or generative AI.

03

Submit & rank

Each submission includes design files, simulated S-parameters, a PDF report, and a method description. Submissions are scored against the challenge's weighted criteria and listed on a leaderboard.

Validate & award

Top submissions are validated by admin and the company. The winner receives the award and may be hired for follow-up integration work. Non-winning solvers retain ownership of their designs (unless stated otherwise).
