By analogy with optics, the term ‘axially-symmetric systems’ is used here to denote radiating structures whose properties are invariant under a rotation about an axis ZZ′, in other words, structures of revolution. They may contain reflecting or refracting surfaces with rotational symmetry, as well as multimode or monomode metallic or dielectric circular waveguides.
