Summary: A design principle has been proposed to achieve the generalized Brewster effect using the generalized Kerker effect, and an adjustable metallic meta-surface has been experimentally designed in the microwave band. This principle allows for easy modulation of incident angles and frequencies, and the validation of the GKE has been shown by achieving the GBE for two different polarized incident waves at the same frequency and angle.

Summary: This study demonstrates that the scattering of a nondiffractive Bessel beam incident field by a perfect conducting circular cylinder can improve the validity of standard physical optics approximation and expand its range of applicability. This offers new effective possibilities for solving various electromagnetic scattering problems.

Summary: Particle roughness has a significant impact on flotation recovery, influencing wettability, kinetics, bubble-particle interactions, and inter-particle aggregation. The effect of particle surface roughness on flotation recovery and its underlying mechanisms have been proven to be important, but current conclusions and findings vary with different materials used. This paper summarizes and discusses the preparation, measurement methods, and effects of particle surface roughness on contact angle, induction time, particle-bubble interaction energy, and flotation effectiveness. A systematic review of literature aims to shed light on inconsistent findings and provide guidance for future studies on surface roughness and particle-bubble interactions.

Summary: This article presents a near-eye display with a triple-channel waveguide and chiral liquid crystal gratings. The waveguide divides the field of view into three parts using polarization orthogonality and angular separation. Experimental results show that the display has a diagonal field of view of 90 degrees, eye relief of 10 mm, transmittance of 4.9%, and uniformity of 89%.

Summary: Near-field acoustic holography (NAH) is an effective tool for accurate sound field reconstruction, but common wave functions may not perform well for elongated sources. To solve this problem, statistically optimized near-field acoustical holography with prolate spheroidal wave functions is proposed. This method effectively reconstructs the sound pressures of elongated sources and performs robustly across a wide frequency range.

Summary: This passage discusses the study of the optical properties of the solar gravitational lens by characterizing the gravitational field of the Sun using multipole moments. By solving Maxwell's equations for electromagnetic waves in the gravitational field, accounting for multipole contributions, and using wave-theoretical methods, the text explores how multipoles affect the optical properties of the lens and cause the appearance of caustics in the diffraction patterns. This new wave-theoretical solution allows for a better understanding of gravitational lensing by realistic lenses with multiple gravitational multipoles.

Summary: In recent research, it has been found that nanofluids composed of base liquids and dispersed solid nanoparticles show an anomalous improvement in thermal conductivity compared to the predicted value. By using various techniques, the study provides solid evidence that the vibrational behavior of liquid molecules around nanoparticles contributes significantly to the increased thermal conductivity. The vibration of liquid molecules is found to be equivalent to phonon conduction in solids, leading to a solid-like behavior in the liquid.

Summary: The study focuses on improving the light absorption and power conversion efficiency of SiNW array transparent solar cells (TSCs) by designing a single SiNW with ultrahigh extinction. Optimizing the symmetry of the SiNW achieved good extinction of natural light, resulting in an 85% improvement in the extinction of the single SiNW. Compared to cylindrical SiNW array TSCs, there was a 23% increase in light absorption and a 14.7% increase in power conversion efficiency.

Summary: Babinet's principle states the equivalence of two problems, where solving one problem solves the other without additional effort. While initially developed for scattering by thin screens, Babinet considered cases where a finite scatterer (like a sphere) was replaced by its shadow (a thin disc). The paper reviews the known information in the context of acoustic and electromagnetic problems and explains the relationship between exact results and the approximations used.

Summary: Internal waves describe the linear response of an incompressible stably stratified fluid to small perturbations, with the reflection characteristics determined by frequency. In critical geometry, weakly viscous and weakly nonlinear wave equations have a solution approximated by a sum of incident wave packet, reflected second harmonic, and boundary layer terms. This result confirms predictions by Dauxois and Young, providing precise estimates on the validity time of this approximation.

Summary: The classical physical optics formulation can lose accuracy in scattered fields when the observation angle deviates significantly from the specular direction, especially in the forward region. This article presents a method to improve accuracy by finding induced currents on the nonilluminated part of the object, reformulating the problem using equivalent currents, and accelerating computation with the multipole expansion of Green's function. This new approach significantly reduces errors in the forward direction compared to the classical PO formulation and has been validated in 2-D scenarios.

Summary: The study introduces a new technique, phase critical angle scattering (PCAS), which allows for simultaneous measurement of bubble size and its transient growth. The PCAS technique shows high resolution in size variation down to several nanometers and high accuracy with errors within 9%, making it a promising tool for studying bubble dynamics.

Summary: The analysis of nano- and microparticle suspensions with micro systems is important in various fields. Currently available microfluidic lab-on-a-chip approaches are mainly used for fluid phase analysis or the use of benchtop particle sizing instruments. We report a new microscale approach to characterize the particle size distribution and absolute concentration of colloidal suspensions.
