Efficient Transfer of the Medium Frequency Magnetic Field Using Anisotropic Metamaterials

This paper introduces a novel waveguide intended for the spatial transfer of alternating magnetic fields. Instead ferromagnetic material, an air core was proposed, while cladding realized using anisotropic metamaterial, built resonators and paramagnetic composite. Since prior works regarding field concentrated on static or high frequency fields, proposed device complements range medium frequencies (several to hundreds kilohertz). The three-dimensional model 50 cm long 20 wide rectangular structure with metamaterial made in COMSOL computed finite element method. Multi-turn inductors were considered homogenized by current sheet approximation, optimization solver used identify optimal design waveguide. analysis respect different permeability material. Additionally, response determined. On these bases, dependencies mean energy density intensity at output characterized. It shown that discussed able provide efficient between two ports. Thus, this can be extend distance wireless power transfer, especially devices isolated thick barrier (e.g., wall), which meta-structure may embodied.
