I'm working with a dielectric ceramic material. I plotted tangent loss V's frequency and it doesn't show any peak which corresponds to the relaxation mechanism. What does this mean? How to interpret the data?
Dear N. Rao
The loss factor is very important in dielectric materials. For more clarity you can check both the graps I.e of real and imaginary part of dielectric vs both temperature and frequency.
Also if you really want to study the relaxation phenomena you can also plot the modulus curves. Which can also tells us about the relaxation is due to single or double.
You can study any of my article regarding dielectric ceramics.
Dear Dr. Rao,
Were you expecting a relaxation mechanism in your material in the frequency range used for measurements? (you did not specify this range, nor the values of the loss tangent you obtained) If so, you could change the temperature and check for the presence of the expected dipole.
My best regards.
Thank you for your answers. I have attached plots of dielectric constant as well as a tangent loss against frequency. I have taken the data in the frequency ranging from 0 to 1 MHz. It may give some hint.
