This letter extends our recent experimental work to detect Brillouin Precursors (BPs) at microwave frequencies through a rectangular waveguide (WG) filled with wet soil. Simulated and experimental data processing methods are discussed. BPs through the waveguide at TE10 mode are shown at two center frequencies. These are then compared with TEM BP at normal incident angles through similar medium. An optimized Brillouin pulse is numerically constructed, and its performance is compared with Lambert–Beer’s law limits.
