The perturbative method for calculating the effect of imperfectly conducting walls on the propagation of electromagnetic waves in cylindrical waveguides is reformulated. The equation for calculating the corrected eigenvalues is obtained in a quite different form. In comparison with the previous result
it is physically more transparent
formally simpler and more compact
and more convenient for practical calculations. 〖JP2〗Special cases overlooked previously are discussed. Results on the coaxial line are presented.〖JP〗
