Experimental and numerical investigation of liquid–solid binary fluidized beds: Radioactive particle tracking technique and dense discrete phase model simulations
TL;DR: In this paper, the behavior of monodisperse and binary liquid-solid fluidized beds of the same density but different sizes is investigated using radioactive particle tracking (RPT) technique and a dense discrete phase model (DDPM).

Ultra-thin subwavelength film sensing through the excitation of dark modes in THz metasurfaces
Sabyasachi Banerjee,Sabyasachi Banerjee,C.S. Amith,Deepak Kumar,Deepak Kumar,Ganesh Damarla,Anil Kumar Chaudhary,Sanket Goel,Bishnu P. Pal,Dibakar Roy Chowdhury +9 more
TL;DR: In this article, the authors demonstrate ultra-subwavelength thin film sensing through experimental and numerical studies of the transmission characteristics of several symmetric and asymmetric planar split ring resonator (SRR) based terahertz metasurfaces coated with thin film of analyte layer(s).

Magnetic wire: transverse magnetism in a one-dimensional plasmonic system.
TL;DR: In this paper, a coupled, cut-wire pair-based metasurface operating at the terahertz frequencies was demonstrated to transform an electric wire to a magnetic wire and vice-versa through asymmetry-induced polymorphic hybridization with potential applications in photonic/electrical integrated circuits.
