Abstract :
This work give a summary of the results of a detailed analysis of EM propagating waves in and around the uniform dielectric coating of a circular cylindrical metal pipe. These results are of value for the diagnostic of anomalies on the surface of tar-coated pipes used in protecting the underground power transmission cables. The results include the distribution of power inside the coating as well the air outside and the number of propagating modes with circumferential variation, and all as a function of frequncy.
