Paper Abstract

The apparatus to measure precisely dielectric constant of a high loss material at f=35GHz has been composed. By using this the complex dielectric constant( ε=ε-jε)of KH2PO4(KDP) has been determined in the temperature region from -160°C to 0°C. The temperature dependence of ε' shows a double peaks around the Curie temperature Tc, which characterizes the critical slowing down of the dielectric response. The maximum values of ε' and ε'' and ε'' reach 480 and 350 near Tc, respectively.
