At high frequencies, wave-matter interactions have to be taken into account and the dielectric permittivity can be no longer considered as a constant when scanning a wide frequency band. In this context, broadband measurements will be additionally helpful to develop realistic and suitable models. Kramers-Kronig relationships are seen as efficient tool to derive broad-band equivalent network representations...
In this paper, experimental characterization of dielectric materials from RF, mm-Wave to THz frequencies accounting for Anisotropy is presented. Broadband extraction of complex permittivity values and dissipation factors for various materials is proposed. A more specific focus is particularly done on a Liquid crystal Polymer (LCP) and passive components on BiCMOS technology with Deep-Trench-Insulator...
