Semi anechoic chamber homogeneity according to IEC 1000-4-3

This paper presents the results of the measurements of the field homogeneity according to the electromagnetic compatibility (EMC) standard IEC 1000-4-3 in a semianechoic shielded room with different kinds of absorbers on the floor. Comparison is made between four configurations on the floor: ground plane, pyramid foam filled with carbon (0.6 m long), ferrite panels, ferrite panels and pyramid foam filled with carbon.
