(Re)Discovering the Lost Science of Near-Field Measurements, Part 4

This is the fourth and final article in our series commemorating 70 years since the advent of modern EMC testing. This last installment discusses the theoretical misunderstandings that arise from the substitution of field intensity for antenna-induced concepts and illustrates the practical outcomes from these theoretical mistakes.

RF Absorption Loss of Shielding Materials

To determine a shielding material’s potential absorption loss capability, you must first know the frequency or frequencies of concern and, second, what shield materials you have available.
