Dieci risultati su cui costruire

Ordinati in base alla facilità con cui è possibile riprenderli: metodo interamente specificato, strumentazione che probabilmente ha già, un esperimento successivo chiaro. Tre delle dieci sono mostrate qui.

Motion-tracking THz-TDS with time-programmable frequency combs

Motion-Tracking Terahertz Time-Domain Spectroscopy Enabled by Time-Programmable Frequency Combs for Moving-Object Sensing

The measurement window is locked electronically onto a moving THz waveform at up to 308 Hz, so the sample no longer has to sit still. Everything needed is in a free preprint, and the hardware is a dual-comb THz-TDS — no new components, the novelty is in the phase-lock set-point control.

Passo successivo point it at a vibrating or conveyor-borne part and see whether thickness or moisture readings survive real production motion. A cheaper half-step is closed-loop feedback on a conventional delay stage.

Quantitative Prediction of Coal-Gangue Content Using THz-TDS and Physics-Informed Machine Learning

An effective-medium-theory-constrained neural network beats random forest, SVR, GPR and a plain ANN on the same data (R² 0.81). The whole feature set — time and frequency domain, refractive index, absorption, permittivity — and the cross-validation protocol are spelled out, and the paper is free with a PDF.

Passo successivo re-run the same pipeline on whatever mixture you already measure — polymers, powders, minerals. The transferable part is embedding a mixing law as a physics constraint, which is what keeps it honest on small datasets.

Resonance-anchored surrogate for absorber design across topologies

Resonance-Anchored Residual Surrogate for Spectral Prediction and Inverse Design of THz Metamaterial Absorbers

Most ML metasurface models must be retrained whenever the geometry family changes; this one predicts resonance frequency and the local spectrum around it across several topologies, and does forward prediction and inverse design in one model. Free, with enough architecture detail to reimplement.

Passo successivo train it on your own simulation library so design sweeps stop costing full-wave runs. Even a partial replication tells you whether the resonance-anchored representation generalises to your geometries.
