摘要：
In this paper, a novel inclusion shape (hi-helix) for artificial magnetic composites is studied. The developed analytical model is used to analyze the eigenmodes and frequency dispersion of the polarizabilities. Experimental investigations (cavity measurements) reveal the main features of the physical phenomena of electromagnetic excitation of individual bi-helix particles. Sheet samples of hi-helix composites are studied by free space measurements. The results lead to the conclusion that the use of new particles can help to improve electromagnetic parameters of magnetic composites. In particular, the magnetic moments appear to be larger than in conventional inclusions, and the resonance frequency of the magnetic permeability is different from that of the effective permittivity.
