The efficiency of wireless power transfer (WPT) system is strongly influenced by the lateral misalignment between the transmitting coil and the receiving coil. To solve this problem, this paper proposed a multi-coil switching coupler to increase the coil lateral misalignment tolerance, in which the transmitter consists of thirteen hexagon coils, including three power supply areas and each area consists...
We propose a fully overlapping domain decomposition method (DDM) for the analysis of small radiating/receiving features situated in electrically large enclosures for EMI/EMC analysis. The proposed method decouples the relatively dense finite element mesh (representing the RF environment of low-noise amplifier front ends and/or output power amplifiers with high fidelity), from a coarse background mesh...
A fully overlapping domain decomposition method (DDM) is proposed for finite element modeling of small features within large domains. The approach decouples the fine mesh associated with antenna details from that of the background domain. This allows for unstructured meshing, providing great flexibility in designing in situ antennas. Another advantage of this algorithm is its faster convergence as...
A precise and efficient finite element model has been developed to solve the coupling of the magnetic field and heating in pulsed coils energized by a capacitor bank. The magnetic field and the current density distribution in each conductor layer of the coil are simulated, taking into account the eddy current, magneto-resistance and heat conduction. The temperature distribution in the conductor during...
The traditional clustering algorithms are designed for large dataset or vary large dataset. It is not easy to cluster the small dataset because of the loss of the statistical character and probability character. In this paper, the class ration is introduced, based on the class ratio, the dynamic clustering algorithm is proposed. The dataset are divided into all possible classes, and the class ratios...
A novel domain decomposition approach for modeling electrically small details within large computational domains is proposed. The approach tackles the conditioning issues associated with highly non-uniform finite element meshes resulting from direct discretization of fine geometrical details. The proposed method addresses this particular challenge, specifically for fast optimization tools, by separating...
