Optimization of Uniplanar Multilayer Structures using Nonlinear Tunable Dielectrics.
Konferenzveröffentlichung, Bibliographie

Kurzbeschreibung (Abstract)

For an optimization of the tunability of coplanar waveguides (CPW) different geometries have been studied on Barium-Strontium-Titanate (BST) thick films. The presented measurement results show a strong dependency of tunability vs. geometry which can not be calculated using standard conformal mapping (CM) approaches. To calculate a cross section of a CPW, a FDTD (finite difference time domain) algorithm expanded to field strength dependent relative permittivities has been implemented. A geometry efficiency factor ? is introduced to review the effective tunability for different geometries.
