Abstract

An investigation has been made of the propagation of electromagnetic waves through dielectric optical guide loaded with conducting sheath helix at the core-clad interface. The guide structure falls into the category of complex media, wherein it has been assumed that the helix sheath remains continuous in nature along with each of the turns being isolated from the adjacent ones. Power confinement factors in the two regions of guide under consideration have been evaluated under the situation of varying values of helix pitch angle - from its orientation being parallel to the optical axis to the perpendicular orientation. Two different illustrative values of guide dimensions have been taken into account, and the effect on the propagation of power have been demonstrated under the variations in helix pitch angle.
