The gap capacitance of a single coaxial resonator is found using a simplified rigorous mode matching method to calculate its resonant frequency. A method of finding the coefficients of the modal field expansions is also shown. The capacitance results for this type of structure are presented graphically and also as a normalised cubic polynomial. The results agree very closely with those obtained from measurements.
