Integro-Differential Analysis of Resonant Magnetic Metasurfaces With Equivalent Medium Approximation

Icaro V. Soares et al.

Summary: This article proposes a strategy to consider the dielectric effects in the thin-wire integro-differential formulation and applies it to analyzing microstrip metasurfaces (MTSs) that support magnetic resonances. The work achieves more accurate results with a homogeneous equivalent medium approximation considering the dielectric properties. Moreover, an experimental methodology is presented to validate this implementation for each device and for the complete system. The proposed formulation is numerically solved with the method of moments (MoM), and the results show close agreement with the experimental data, leading to a significant reduction in computation time compared with a full-wave analysis.

Comparative Evaluation of Different Cables for Magnetic Couplers in Inductive Power Transfer Systems

Jesus Acero et al.

Summary: This work evaluates several alternatives to traditional copper litz wires, including aluminum litz wires, copper-clad aluminum litz wires, and copper tubes. The potential benefits of these alternatives, such as weight and cost savings, are considered. However, the resistance of the magnetic coupler is a key factor that needs to be addressed. Therefore, a model combining analytical formulas and finite element simulations is proposed to calculate the resistance of each cable. The model is verified with resistance measurements using various prototypes, and the results provide insights into the suitability of the frequency range of use.
