Cut-off wave number and dispersion characteristics of eccentric annular guide with dielectric support

The paper presents a rigorous analysis of a uniform waveguide with circular outer conductor and eccentric inner conductor supported by dielectric slab between the inner and outer conductors. A vector finite element approach in which non-physical spurious solutions do not appear has been followed to study the cut-off frequencies of higher-order modes as well as dispersion characteristics of this guiding structure. Numerical data on cut-off wave numbers and dispersion characteristics have been presented.
