Determination of the Complex Dielectric Constant of Liquid Dielectrics in the Microwave Region

Sažetak

Transmission of electroil)agnetic radiation through a waveguide is descr
ibed by equations using as parameter the dielectric constant of the medium filling the waveguide. Liquids are particularly suitable for measurement because of their complete filling of the waveguide cross section. Thus equations of electromagnetic wave transmission need not be modified for losses through the gap between the waveguide and the sa'mple. In the literat ure a similar measurement with solid samples1 has been described which requires a knovledge
of the dielectric constant in order to calculate dielectric conductivity.
In liquids it is possible to change the thickness of the samp le, whereby
additional information needed for the simultaneous determination of the
dielectric constant and dielectric losses i s obtained.
