  • Abstract
    Characterization of complex permittivity has been performed using circular cylindrical cavities. For this reason, perturbed TE11p odd modes have been analyzed. Closed-form expressions are given for the relative dielectric constant εr and the loss tangent tanδ for an inserted rectangular specimen. Experimental results are presented for the verification of the derived formulas. The use of circular cylindrical cavities instead of rectangular ones offers the advantage of higher Q factors and, therefore, higher accuracy.
