Abstract
In the present paper, the field internal to an infinite-strip plane-parallel mirror resonator is evaluated in the case when the structure is illuminated by a cylindrical primary wave. The feeder where the primary wave orginates constitutes a perturbation of the resonator and is assumed to scatter a cylindrical wave proportional to the field impinging on it. The quasi-stationary field pattern internal to the structure is evaluated for several values of the efficiency of the scatterer, that is, of the factor relating the wave scattered by the feeder to the wave impinging on the feeder. Resonant frequencies and fields are compared with the resonant frequencies and fields of a Fabry-Perot resonator not perturbed by the presence of the feeder. The effect of the persistent primary wave alone is analyzed by considering the case of a feeder with vanishing efficiency.
