Brief Measurement
Theory
The permittivity measurement setup is shown in Figure 4-1. The
analyzer can measure relative permittivity of a plate shaped, solid
dielectric material.
Figure 4-1. Dielectric Material Measurement
The analyzer calculates the relative permittivity from the measured
admittance . The calculation equation is:

Note
The above equation is ideal, in fact, the equation in which the edge
eect and parastic error of test xture is condidered is used. F or
