Abstract :
In the letter we present a new method for the calculations of resonant frequencies of cylindrical dielectric resonators using the variational principle. This method is applicable for determining the resonant frequencies of cylindrical isolated and shielded dielectric resonators. Computations for all modes (TE, TM and HEM) are given.
