| dc.description.abstract | An investigation of the dispersion and
attenuation characteristics of cylindrical structures
supporting guided electromagnetic waves with low
attenuation is described. The object of the investigation
is to understand how the cross-sectional shape and the
nature of the boundary conditions affects the propagation
characteristics. Attention is directed towards structures
supporting the least number of propagating modes under the
conditions which yield low attenuation over a reasonable
bandwidth. Elliptical waveguides with both smooth-walls
and corrugated walls are studied in detail. This reveals
errors in previous-theories which are corrected. Some
aspects of corrugated rectangular and circular waveguides
are considered. Potential low attenuation waveguides such
as the dielectric lined and dielectric waveguides are
evaluated. | en_US |
