Mimicking the Perfect Electromagnetic Conducting Scattering Mechanisms with Suitable Bi-Isotropic Media

The perfect electromagnetic conducting boundary is an intriguing conception with multiple potential applications; however, the physical mechanisms that can simulate a similar behavior is not yet completely identified. This work considers an electrically small cylindrical perfect electromagnetic conducting boundary for which the scattering effect is mimicked by suitable bi-isotropic media. The derivation of their optimal parameters is based on the Taylor expansion of the omni-directional terms; nonetheless, a post-correction is required to obtain reliable results for any kind of excitation and for any spatial harmonic. However, the advantage of this optimal solution is its non-extremal magnitudes, which render the practical realization more feasible. The present study, which is valid only for a thin perfect electromagnetic conducting wire, could play the role of the unit cell when treating more sizable perfect electromagnetic conducting configurations of arbitrary shape and curvature.
