Abstract
A formalism based on plane-wave decomposition is applied to the linear propagation of terahertz pulses in experimental geometries. The approach is general and is not restricted to any particular polarization (or current) source. Near- and far-field expressions easily amenable to numerical computation are obtained for the temporal profiles and spectra of terahertz pulses in layered structures, as often encountered in experiments. The effects of polarization and angle-dependent multiple reflection and transmission, as well as of material dispersion, are included. Examples of optical rectification in GaAs and ZnTe are presented to illustrate the simplicity of the method and are compared with experiments. The numerical evaluation of the expressions for the terahertz electric field in practical experimental geometries is straightforward.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
