| Popis: | An experimental realization of a magnetic Fano-like resonance-based cylindrical cloaking scheme in the microwave frequency regime is presented in this paper. Fano-like resonance is excited by the coupling between the background electric dipole mode and the dark magnetic resonant mode in the composite. The excitation of Fano interference patterns significantly reduces scattering from the composite at resonance in the microwave regime and hence the target becomes undetectable from backscattering measurements. Multipolar scattering theory has been used to clarify the excitation of this Fano resonance and the designed cloak is characterized using monostatic and bistatic scattering measurements inside an anechoic chamber. |
