Enhanced Full-Wave Circuit Analysis for Modeling of a Split Cylinder Resonator

An enhanced full-wave method based on circuit analysis is presented in this paper, where the whole set of modes TE
_mnp
and TM
_mnp
are taken into account. The modeling of a split cylinder resonator is done with two circuit networks of one and three ports, characterized by their generalized admittance matrix, which is computed making use of the mode matching method. The improved full-wave circuit method has been applied to the accurate determination of dielectric properties of materials. The proposed method has been validated through comparisons with other published models and also with measurements.
