On the use of dipole models to correlate emission limits between EMC test facilities

Simple formulas are developed that enable emission limits from one EMC facility type to be translated to other EMC facility types. Facility types considered are free space, a half space as represented by an open area test site or a semi-anechoic chamber, TEM cells, and reverberation chambers. The formulas are based on simple dipole models. The formulas can provide valuable guidance for standards and product committees in setting product emission limits.
