Explore how plane waves bend and diffract around a wedge and what that means for real-world weather and radar signals. This work presents a clear, step‑by‑step treatment of diffraction by a dielectric wedge and its practical application to radio propagation through a cold front. It blends geometrical optics with full wave solutions, showing how different polarizations behave and how cylindrical diffracted waves emerge from the problem. The discussion grounds theory in realistic assumptions, making the results usable for engineers and physicists working with atmospheric or radar scenarios.
The text develops the two‑dimensional reduction, lays out the geometrical solution, and then derives the complete field by considering reflected, refracted, and diffracted components. It explains how the barrier lines and region boundaries shape the observed wave patterns and how the transition from plane to cylindrical waves occurs in detail. The final portion connects the diffraction theory to atmospheric propagation, offering practical guidance for analyzing signals affected by cold fronts.
