Within the joint European project TEMCA2 a new procedure to test the radiated emissions of large machines was suggested. Instead of antennas it uses a simple wire structure to detect the radiated emissions. A new set-up of this wire structure using c

Some theoretical and practical aspects of the development of isotropic electric field probes regarding the influence of supporting dielectric materials are presented. Three effects of the normally neglected field distortion caused by the support will

The method of moments (MOM) has proven to be one of the most valuable tools for EMC-analysis. Extending this method by transmission line theory, considering distributed sources, in conjunction with the complex cable transfer-impedance, delivers the p

The paper presents a method to determine the complex cable transfer impedance of shielded cables. This method is based on a combination of measurements and computations and allows one to handle multiwire cables too. Some curves of the complex transfe

In this contribution, the investigations to minimize the interference coupling into standard coaxial cables with braided shield are described. Considering the transfer impedance as the coupling describing quantity, it is shown that reducing the cover

The hybrid method, HM, which is a combination of the method of moments (MoM) and the uniform geometrical theory of diffraction (UTD) has been extended in the sense, that a new class of geometrical structures is accessible now. The limitations so far

The cable transfer impedance is a quantity which describes the quality of coaxial cables. For analyzing the interference coupling into a shielded cable, precise knowledge of the transfer impedance is necessary. For analysis within a frequency range,

A geometrically extended version of the uniform geometrical theory of diffraction (UTD) was introduced. In its classical form the UTD was limited to canonically shaped scattering objects. It was shown that the surfaces can be described by parametric
