One analytical tool for analyzing these objects is a technique which decomposes them into their 1D equivalents, called the effective index method, while Marcatili's method for analyzing them relies on the assumption that their fields are confined to the core. In the case of perturbed boundary conditions, the attenuation constant beta of the mixed modes in these structures takes on a value dependent on the average of the betas of the orthonormal modes minus a term dependent on the mode coupling. For each solution of the eigen value problem within these structures, transverse propagations can only occur at frequencies above the cutoff frequency. If the ends of one of these objects is closed, a resonant cavity is obtained, and like a cavity, the field inside one of these objects is described by a combination of TE, TM, and TEM propagations. For 10 points, identify these open-ended tubes which can be either cylindrical or rectangular, and which are designed to propagate electromagnetic radiation.
