Abstract : It is shown that, in principle, for certain monotonically decreasing inhomogeneous, toroidally-shaped media, wave functions and real numbers exist. The waves are confined to a certain central region depending on the type of media, the density profile and the mode order. Thus, it would appear that resonators of this type can support bound waves and thus they can be used to store electro-magnetic energy (photon capacitor) or in the case of active media the structure may support laser modes. The type of inhomogeneous toroidal resonator described is still in its initial stages of conception and development. Questions such as the optimal media and how the efficiency of the toroidal inhomogeneous resonator compared with that of other kinds of resonators still remain to be answered. (Author)
