ASTM D 4935-10: Standard Test Method for Measuring the Electromagnetic Shielding Effectiveness of Planar Materials

The ASTM D 4935-10 standard involves the measurement of shielding effectiveness of planar material (square) for plane far-field Electromagnetic wave. An illustration of such is shown in the Figure 1. The samples under test must be electrically thin for a near field magnetic field (H) calculation. Electric field shielding effectiveness can be calculated for far-field as well, but applicability has yet to be established. Measurements are to be taken within a frequency range of 30 MHz – 1.5GHz.
