Abstract
In this paper a numerically efficient algorithm is developed for solving the problem of nonaxisymmetric wave propagation in cylindrically layered media with horizontal discontinuities. For an off‐axis source in cylindrically layered media, because the nonaxisymmetry of the waves gives rise to the vectorial coupling between TE and TM waves, the modeling of the wave propagation becomes much more difficult than for a centered (axisymmetric) source. However, the numerical mode‐matching method proposed here calculates very efficiently the electromagnetic fields in cylindrically layered media with horizontal discontinuities. Several numerical examples are given to verify the numerical method and to illustrate the applications of this method in the calculation of the field generated by a magnetic dipole source.
