- Abstract
By the example of a cylindrical cavity with an annular slot, resonance conditions in cavity resonators with slots in the perfectly conducting walls are theoretically studied. The stationary electromagnetic fields of eigenmodes are described in terms of the partial domain method with the use of the homogeneous Maxwell equations. The complex wavenumber and other parameters of these fields are determined from the condition that the fields are continuous on the slot boundaries. An energy resonance condition is formulated that requires that the energy flux of the resonance field through the slot be minimal. It is shown that these conditions, taken together, remove infeasible (nonphysical) solutions to the homogeneous problem, which are associated with out-of-cavity excitation sources.
