Time-domain magnetic shielding of a thin conducting screen against a small loop

The classical electromagnetic problem represented by a small loop axially parallel to a thin conductive planar shield of infinite extent is addressed in the time domain. The problem is solved analytically through a modified Cagniard-de Hoop approach and numerically through the double inverse Hankel/Fourier transform. Although some approximations are made, the analytical method is the most useful in predicting the main time-domain shielding characteristics.
