“…However, the first attempt to study surface wave propagation over a coated conductor with small cylindrical curvature in the direction of propagation was reported by Horiuchi (1953) from the Laboratory of Communication Instruments, Tokyo, Japan. The outline of how to study the wave fields in this case was suggested on the basis of the system of plane conductors studied earlier.…”

Azimuthal surface waves are eigenmodes of cylindrical plasma–dielectric–metal structures both in the presence of and without an axial static magnetic field. They are actively studied due to possible applications in plasma electronics, nanotechnologies and biomedical diagnostics. Higher radial modes are known to propagate at higher frequencies and shorter wavelengths compared to those of the zeroth mode, a feature which is of interest for practical applications. To gain the advantage of the excitation of higher radial modes of azimuthal surface waves one has first to know their dispersion properties. This paper generalizes the results of earlier papers by including a static axial magnetic field and considering the higher radial modes. The presence of the constant axial magnetic field removes the degeneracy in the wave spectrum with respect to the sign of the azimuthal wavenumber.

The problem of radiation from a uniform bend of step‐index single‐mode fibers is analyzed in detail. Unlike the previous methods of approximate evaluation of the bending loss of fibers, a strict analysis of the radiated electromagnetic fields is performed. A detailed study of the electromagnetic fields, radiated in the neighborhood of the junction of straight and bend portions, which have not been studied fully so far, is performed here. The radiated field is expressed in integral form, using the mode field on the curved surface circumscribing the core in the cladding, and the far field expressions are determined using the stationary phase method. From these results, many factors that had not been clarified before such as the degree of contribution of mode field components and radiated power, the direction of travel of radiated light, and radiation patterns, etc., are evaluated in detail in addition to the evaluation of radiation losses with greater precision. Moreover, the numerical examples for the radiation from the starting portion of a bend in the curved fiber, and the radiation patterns in the fiber cross‐section plane when radiation is uniform, are also shown.
