Analysis of Fields in Microwave Open Resonators with Detail on Perfect and Imperfect Mirrors

Recently completed computations of the field profiles existing within various microwave open resonator configurations are described for the following situations - perfectly aligned planar and spherical mirrors; misaligned spherical mirrors; imperfectly shaped spherical mirrors. The approach used, involves the sequential projecting of the field profile existing at one mirror on to the other until a steady state profile is obtained. The relative merits of two calculational methods are discussed. Results are presented for the various configurations.
