A product qualification gave very different results for CDM testing between three labs. This paper describes the investigation into the root cause of these differences. The most relevant issues are the measurement bandwidth and the quality of the calibration modules. An improved procedure is proposed.

Theory of scattering by lossy dielectric, ferrite and/or conducting cylinders is investigated using a combination of an iterative scattering procedure and the orthogonal expansion method. The addition theorems for vector cylindrical harmonics, which transform harmonics from one coordinate system to another, are presented.
