A new time domain approach for determining the dielectric constant using stripline geometry

A novel time-domain approach to determining the dielectric constant of materials using stripline geometry is presented. The technique uses time-domain reflectometry measurements and computer simulation to determine an optimum lossy transmission line model characterizing the stripline under test. The line model is then used for determining the dielectric constant of the dielectric material. Experimental and simulated results are presented to verify the validity of the technique, which is demonstrated by using two striplines constructed from composite laminates.<
