For the analysis of light propagation in photonic guided-wave ring microresonators, leaky mode solvers for bent channel waveguides are often used. In the analytical approach, the leaky mode field is expressed in terms of cylindrical functions of complex arguments and a complex order which plays a role of the /azimuthal/ propagation constant. In this contribution we present a modified approach which takes into account the circular symmetry of the stucture. We calculate the eigenmodes of a lossy microresonator as modes with complex eigenfrequencies. In this approach, the eigenmodes are described by cylindrical functions of an integer order and a complex argument. Similarities and differences of both approches are demonstrated using simple examples of 2D /planar/ structures.
