The paper presents the electromagnetic (EM) wave
propagation in cylindrical optical fibers with helical windings under
slow- and fast-wave considerations. Field components are deduced
for both the cases, and also, the dispersion relations are obtained
by applying the boundary conditions, as modified by the presence
of conducting helical windings. Two special cases are considered
corresponding to the values of the helical pitch angle as 0◦ and 90◦. A
comparison of the dispersion relations is presented. |
