The transition matrix, frequently abbreviated as T-matrix, contains the complete information
in a linear approximation of how a spatially localized object scatters an incident field. The T …

In this study, the nonlinear optical phenomena emerging from the interaction between vortex
and vector beams and achiral nanoparticles or nanostructures are investigated. Despite the …

Polarization-dependent dynamical properties of light such as the spin angular momentum
(SAM), helicity, and chirality are conserved quantities in free space. Despite their similarities …

The multipolar expansion of the electromagnetic field plays a key role in the study of light–
matter interactions. All the information about the radiation and coupling between the incident …

We investigate how the near-field enhancement of self-similar nanolenses, made of three
plasmonic nanospheres with decreasing sizes and separations, is affected by quantum …

Researchers routinely characterize optical samples by computing the scattering cross-
section. However, the experimental determination of this magnitude requires the …

The search for objects that yield maximum electromagnetic chirality in their emitted wave
field has gathered significant attention in recent years. However, achieving such maximum …

抄録 物質は光の電場と磁場に対して異なる応答を示すため, 円偏光状態の光をナノ粒子に照射
すると, 一般に光のヘリシティ (円偏光の回転方向) は保存されない. ところが …
