Resonant frequency of cylindrical dielectric resonator placed in an MIC environment

An effective dielectric constant technique to determine the resonant frequency of the TE_01δ mode of a cylindrical dielectric resonator placed in a microwave integrated circuit (MIC) environment is discussed. An expression for the dielectric constant ε_eff which makes it possible to obtain results that compare favorably with rigorous methods is given. Experimental results demonstrating the method´s validity are also reported. For a given resonant frequency, closed-form expressions for computing the height of the resonator are given
