Three-Dimensional Micromotion Signature Extraction of Rotating Targets in OFDM-LFM MIMO Radar
TL;DR: In this article, the Hough transform and Orthogonal Matching Pursuit (OMP) algorithm are introduced to extract the m-D curve features from echoes, and then the 3D micromotion signatures of the rotating targets are obtained by solving nonlinear multivariable equation systems.
Full-wave analysis of extraordinary backscattering by a layered plasmonic nanosphere
TL;DR: In this paper, an exact full-wave analysis of plane-wave scattering by a multilayer nanosphere is proposed, which is then used to study the behavior of N-layered plasmonic spherical particles.
On the Integral Identities Consisting of Two Spherical Bessel Functions
TL;DR: In this paper, the authors revisited thoroughly the evaluation of the integral of IL,l'(kappa,kappa'), and provided the correct solution to the integral in spherical coordinates in terms of distribution.

Steering valley-polarized emission of monolayer MoS 2 sandwiched in plasmonic antennas
TL;DR: It is demonstrated that a chiral plasmonic antenna consisting of two stacked gold nanorods can modulate strongly valley-polarized photoluminescence of monolayer MoS2 in a broad spectral range at room temperature.

Electromagnetic Scattering by a Gyrotropic-Coated Conducting Sphere Illuminated From Arbitrary Spatial Angles
TL;DR: In this article, a Mie-based scattering theory for a gyrotropic-coated conducting sphere such that an arbitrary incident angle can be modeled analytically from an eigen-system determined by gyroropic permittivity and permeability tensors is presented.
