the ratio of the energy lost to the energy stored. Figure 3. Loss tangent vector diagram The loss tangent or tan d is defined as the ratio of the imaginary part of the dielectric constant to the real part. D denotes dissipation factor and Q is quality factor. The loss tangent tan d is called tan delta, tangent loss or dissipation factor.
