Determination of the parameters of one-dimensional globular dielectric structures in the microwave range using a biconical resonator

The application of a biconical resonator for determining the parameters of one-dimensional globular periodic dielectric structures is considered. The HE111 resonant mode provides an effective estimate of the permittivity of the material from which the globules are made. The procedure for estimating the parameters includes the use of a fractional-rational approximation of the analyzed frequency characteristic. A numerical simulation of the electromagnetic field for a biconical resonator with the studied structure was implemented. The possibility of obtaining estimates of effective dielectric constant is verified using experimental data for a one-dimensional structure of contacting spheres placed in a dielectric tube.
