Summary: This paper presents the design and experimental verification of a linear polarization metasurface converter with arbitrary polarization rotating angle and stable oblique incident response. By changing the transmission line length of the metasurface unit cell, different polarization rotation angles can be achieved. The experimental results confirm that the proposed metasurface polarization converter has a high polarization conversion ratio under up to 50° oblique incident wave.

Summary: By utilizing the fundamental electromagnetic properties of metasurfaces, we have developed a platform for classifying reciprocal bianisotropic metasurfaces and determining their isotropic, anisotropic, bi-isotropic, and bianisotropic properties. We have provided experimental guidelines for identifying each class using macroscopic scattering parameters, such as reflection and transmission coefficients, under plane wave illumination with linear and/or circular polarization. We have also clarified common confusions in the classification of anisotropic and chiral metasurfaces based on circular dichroism measurements.

Summary: This study investigates the effect of different polarization states of excitation light on the unpolarized Raman spectra of unstructured samples. The results demonstrate that the intensity ratio of Raman peaks varies depending on the polarization state of the excitation light. Specifically, the intensity of peaks related to functional groups and C-H stretching modes increases when circular polarization is applied, which is beneficial for studying liquid mixtures with low concentrations.

Summary: The fixed linear-polarized conical beam transmitarray is superior to the radially linear-polarized conical beam antenna in certain applications. This paper presents a method to obtain conical beams with fixed linear polarization (FLP) and circular polarization (CP) using a pencil beam source to illuminate a transmitarray. The transmitarray elements are distributed on rings for good circumferential symmetry, and the dimensions of the double-ring elements are adjusted to compensate for the phase delay. Three different cone angles of the FLP conical beam transmitarray are designed and fabricated. The simulated and measured results show good agreement, demonstrating the effectiveness of the proposed method.

Summary: Zirconium-based metal-organic frameworks, specifically UiO-66 and related frameworks, have been extensively researched for chemical warfare agent decontamination, but their potential for sensing applications is relatively unexplored. This study introduces a simple and rapid microwave assisted synthesis method for growing oriented UiO-66 thin films on unmodified silicon and gold substrates. Additionally, the synthesis of Zr/Ce solid solution thin films of UiO-66 on gold is described, along with the utility of the microwave method for functionalizing sensor architectures with UiO-66 thin films.

Summary: A stochastic effective model based on atomic-scale characterization of electrode surfaces was developed to generate probability density distributions of work function and field enhancement factor. In the simulation, each simulated surface element draws work functions and betas for many independent atomic emitters, with the emitted current computed by summing each atomic emitter's current. The model shows reasonable agreement with measured emitted currents across a range of electric field values.

It explores the factors influencing electron emission propensity and systematically examines different missing row reconstructions on the Pt(110) surface. The findings suggest that narrow (111) nanoterraces on free Pt surfaces exhibit a local energetic stability, potentially serving as a common structural feature in complex surface morphologies.
