Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces

Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.
Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

Scattering Analysis of Large Scale Cavities Using the Non-standard FDTD Method [PDF]

大型構造体の高精度な散乱解析法としてNS-FDTD法が提案されている.しかし, 従来のNS-FDTD法は等方格子のみでの定義しか行われておらず, 任意のCavity形状を取り扱うには制限が大きい.本論文ではこの制限を取り除くために, NS-FDTD法をより汎用性のある非等方格子へ拡張する.まず, 非等方格子でのFD Laplacianを新たに定義し, その1階差分演算子による分解表示から非等方格子のNS-FDTD計算式を導出する.また, NS-FDTD法で用いるNS-FD法の物理的意味付けを行う.次に,

Hierarchical VO2@BiVO4 Films Decorated With Porous BiVO4 Nanoplates for Durable and Self‐Cleaning Smart Windows

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT VO2 is a promising thermochromic material, but it is still limited by low transparency, weak solar modulation, and poor stability. Here, we develop a coordination‐compound‐derived strategy to construct a hierarchical BiVO4/VO2@BiVO4 film with a core–shell@nanosheet structure.

Numerical Dispersion and Stability Condition of the Three Dimensional Non-standard FDTD Method [PDF]

FDTD解析における位相誤差を縮小するためにNS-FDTD法がColeによって考案された。しかし、Coleの論文では数値分散特性及び正確な安定条件が示されていなかった。また、等方格子のみでの定義しか行われていなかった。本論文では、3次元NS-FDTD法を非等方格子に拡張し数値分散特性及び安定条件を求めた。安定条件の解析より、本手法の安定条件はFDTD法よりも大きいことが示された。数値分散特性の解析より、等方格子、非等方格子いずれの場合においてもFDTD法に比べてはるかに高い精度をもつことを示した ...

Wafer‐Scale Deterministic Fabrication of Axis‐Ratio–Engineered Silicon Nanoparticles for On‐Resonance Electric–Magnetic Dipole Interference

Small, Volume 22, Issue 32, 8 June 2026.
Wafer‐scale top‐down fabrication yields silicon nanoparticles with exceptional uniformity (CV 1.7%–2.4%), enabling deterministic axis‐ratio tuning. At AR ≈$\approx$ 2.1, electric–magnetic dipoles overlap on‐resonance, producing near‐Kerker forward scattering (F/B ≈$\approx$ 12.5).

On the Treatments of TE Mode Edge Conditions in the FDTD Method and Its Applications to the Microwave Circuit Analysis [PDF]

FDTD解析におけるエッジ条件の取扱いについてはTM波及びTE波に関して種々の報告がなされている.しかしながら, TE波における解析式はFDTD法の節点配置の都合上実用的な解析式はなかった.本論文では導体エッジ部がFDTD解析で通常用いられる格子の中央に位置する場合についてTE波のエッジ条件解析式の導出を試みた.その結果, 簡便かつ実用的な式が得られた.応用例として, マイクロストリップアンテナ及び容量性Iris装荷導波管の解析を行い, 本手法の有効性を確認した.journal ...
