In this article, a decomposition approach for the computation of beam coupling impedances is proposed. This approach can account for the mutual electromagnetic coupling in long accelerator structures consisting of several consecutive segments. The me

Wideband modeling of complex loss-free isotropic RF structures is a challenging task in electrical engineering. This paper presents a new formalism to create compact wideband equivalent models of complex RF structures. In a first step, the complex st

In this paper, we demonstrate the discontinuous Galerkin finite-element method (DG-FEM) used for the computation of electromagnetic fields in the interior of 3-D structures with open waveguide ports. This method is particularly applied to derive freq

The possible effects of high-frequency electromagnetic fields (EMF) on biological systems are a subject of public concern and scientific discussion. It is generally accepted that the absorption of part of the field energy may cause a temperature rise

Es wird eine Methode zur Berechnung der Hochfrequenz-Eigenschaften komplexer Strukturen vorgestellt. Das Verfahren beruht auf der Zerlegung der Gesamtstruktur in einzelne einfachere Segmente, deren breitbandige S-Matrizen mit kommerziellen Programmen

Large rf-structures are sometimes too complex to be calculated entirely in single simulation runs. Usually, if the structure has open ports, the scattering properties - the so-called S-parameters - are of primary interest. As a matter of fact, they c

In this paper, four thermo-pneumatic driving concepts for volume actuators based on printed circuit board technology (PCB) are presented. Several experimental measurements have been realised to quantify the power consumption and the behaviour of the
