Abstract

Radiation characteristics of infinitesimal dipole in multilayered circular cylindrical structure including gyromagnetic media are investigated. Transversal field equations in spectral domain are obtained for gyromagnetic medium in cylindrical coordinates. These expressions are formed into a set of linear differential equations. The solution at each layer is expressed in terms of state transition matrices. Fields are matched at the interfaces. Far fields are evaluated asymptotically. The effects of changing the bias field, the thickness of the layers, the frequency, and the medium parameters are examined.
