Optimal helix shape: Equality of dielectric, magnetic, and chiral susceptibilities
Tóm tắt
The possibility of linearly polarized electromagnetic microwave conversion into a circularly polarized wave using single-turn helices with preliminary calculated optimal parameters is demonstrated. The helices are characterized by equal dielectric, magnetic, and chiral susceptibilities. Such optimal helices can be further used, for example, to develop reflectionless coatings and metamaterials with negative electromagnetic wave refraction. It is demonstrated that the examined helices activated by both electric and magnetic fields, that is, for any arbitrary orientation of the incident wave polarization plane, have optimal characteristics. This is the advantage of the optimal helices over other possible metamaterial elements, for example, rectilinear vibrators or circular resonators.
