“…Due to their widespread and important applications in magnetic materials, 1,2 electronic devices, 3,4 bioimaging, 5,6 synthesis, 7,8 catalysis, 9,10 materials science 11,12 and nuclear technologies, 13,14 there has been burgeoning interest in the fundamental chemistry of the f-elements over the past few decades. Since f-element metal ions, that is group 3, lanthanide, and actinide ions, are hard Lewis acids with typically large radii and high coordination numbers, they preferentially bind with hard bases (by the hard–soft-acid-base definition); the chemical bonds of these ions are understood to be predominantly ionic, thus their solution chemistry is dominated by N-, O-, and halide-donor ligands.…”

“…The sample SMD inductor used in this paper is SPM6530T-2R2M-HZ from TDK [13]. The measured S-parameter can be converted to ABCD parameter using (1), and then the impedance of an inductor can be expressed using (3). This method has the advantage of accurately measuring the impedance of the device under test(DUT) without the need for de-embedding.…”

“…According to TDK's power inductor SPM series product overview [2], it indicates that it can accept a large current compared to ferrite, has low DC resistance, can be manufactured in a small size, and has superior DC bias characteristics. Moreover, because of their high Curie temperature, these inductors show a small change in characteristics with ambient temperature, have good shielding qualities, and experience minimal magnetic flux leakage due to the coils being integrally molded with metallic magnetic powder, and it is also known that Fe-Si based alloy has a higher magnetic saturation density [3,4]. With all this superiority, Fe-Si based alloy powder has been employed for the magnetic core material of the SMD inductors in the automotive applications with its relatively low permeability(from scores to hundreds) compared to other ferromagnetic materials.…”

In this paper, we propose a methodology for analyzing the near-field coupling between two surface mount device (SMD) inductors using a 3-dimensional electromagnetic (3D-EM) model. To develop the 3D-EM model, we first extract the effective permeability of core magnetic material in the SMD using the loss tangent in the equivalent circuit model. Then the effective permeability is used in the magnetic material for the 3D-EM modeling of SMD inductor. The validity of the proposed 3D-EM model is confirmed by comparing the impedance and S-parameters obtained from both measured and EM-simulated values for the two near-field coupled SMDs. Finally, the near-field coupling effects between the two adjacent SMD inductors are visualized in terms of magnetic coupling path visualization (CPV) using the proposed 3D-EM model, which demonstrates its usefulness for near-field coupling analysis.

In this paper, we propose a methodology for analyzing the near-field coupling between two surface mount device (SMD) inductors using a 3-dimensional electromagnetic (3D-EM) model. To develop the 3D-EM model, we first constitute the equivalent circuit of the SMD inductor from the measured impedance and derive the loss tangent using circuit parameters. Secondly, the loss tangent using damped harmonic oscillator model is introduced to extract the effective permeability of core magnetic material in the SMD inductor. The optimization algorithm is used to compare the two loss tangents. Then the effective permeability is used in the magnetic material for the 3D-EM modeling of the SMD inductor. The validity of the proposed 3D-EM model is confirmed by comparing the impedance and S-parameters obtained from both measured and EM-simulated values for the two near-field coupled SMD inductors. Finally, the near-field coupling effects between the two adjacent SMD inductors are visualized in terms of coupling path visualization (CPV) using the proposed 3D-EM model, which demonstrates its usefulness for near-field coupling analysis.
