摘要: The influence of bulk losses and dispersion on the propagation properties surface waves in a radially inhomogeneous optical fibre is investigated numerically. assumed to consist homogeneous cladding either infinite or finite extent core higher permittivity. Bulk materials are presented by frequency-dependent complex permittivities. Power series expansions for electromagnetic field quantities have been used attenuation phase coefficients lower order modes calculated Results two different permittivity profiles, viz. parabolic profile cubic spline profile, being this case. Also, diameter numerical results discussed.
