In this paper, we present a novel miniaturized MNG (-negative) metamaterial loaded cylindrical cavity resonator based on the existence of surface waves at the interface between a metamaterial and an ordinary medium. First, we formulate the general dispersion relation for such a resonator and we show that this configuration may in principal provide the miniaturization possibility. A category of settings which provide maximum degree of miniaturization are determined. Quality factor variations are also calculated theoretically and finally a design example with the resonant frequency of about 1.39GHz, 94% miniaturization, and a relatively high quality factor of about 4500, comparing with the other miniaturized metamaterial resonators, is presented and also numerically simulated. The simulated results verify the accuracy of analytical calculations.
