Electromagnetic field generated by an off-axis source in a cylindrically layered medium with an arbitrary number of horizontal discontinuities

Investigates the propagation of electromagnetic waves in a cylindrically layered medium with an arbitrary number of horizontal discontinuities. A coupling exists between the transverse electric and transverse magnetic components of the field even in the absence of the horizontal discontinuities, which makes is difficult to solve for the field. An efficient numerical mode-matching (NMM) algorithm is applied to tacke this 2.5-D problem. For several special geometries, the numerical results from this NMM algorithm is compared with analytical solutions as well as the earlier numerical results for axisymmetric cases. -from Author
