Optimal Penetration in Debye-Model Dielectrics Using the Brillouin Precursor Pulse

With proper initial conditions, interrelated phase and attenuation dispersion effects modify an ultrawideband pulse into precursor fields. Because of its minimal decay in a given Debye-model dielectric, a Brillouin precursor pulse possesses near optimal penetration that is bounded above by the spectral maximum frequency-chirped Lambert-Beer's law limit and below by the effective frequency-chirped Lambert-Beer's law limit, making it ideally suited for ground and foliage penetrating radar as well as through wall and medical imaging.
