Abstract :
A method for calculating the unloaded Q of hybrid modes in a dielectric loaded resonator is described. The method is applied to a 33 GHz resonator on a GaAs substrate. The contribution of the losses in each of the resonator´s elements is computed separately. It is shown that the hybrid modes can have substantially higher Q´s than the TE modes. This result is particularly significant for millimeter waves
