High-Frequency Dielectric Spectroscopy (1 MHz < ν < 40 GHz)

In this radio and microwave region, standard dielectric techniques employing BNC-cable connections no longer work and specially designed rigid coaxial lines are used. Especially in the GHz region, some special "know-how" is necessary to obtain reliable results.
