摘要：
In this paper, a novel broadband (0.9-10 GHz) measurement method for the complex dielectric constant based on only one cylindrical resonator and iteration algorithm is proposed. To overcome the difficulty of mode recognition and provide sufficient selections of working modes at high frequency, multiple TMmno modes are selected as working modes, which are different from the traditional TM0n0 modes. Three materials with different dielectric constant and loss are simulated for demonstration, showing that a relative error of the real part of the dielectric constant of no more than 1.3% is achieved.
