Theory of ground-penetrating radars III [PDF]
jiip, 1998 Abstract - The governing equations are Maxwell’s. The source of the current is either j = ey δ(z − z 0)δ(x)f(t) or eϕ δ(z − z 0)δ(r − r 0)f(t) (straight wire or loop of current, f(t) is a pulse).

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments
Advanced Functional Materials, EarlyView.We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.
