Summary: A rigorous calculation on total internal reflection in the presence of absorbing second medium reveals various behaviors, including smaller angle of refraction, decreasing absolute value of reflection coefficient with increasing absorption, and phase changes of reflection coefficient at different incident angles. Energy conservation law is confirmed at the boundary between the two media through calculation of the time average of the Poynting vector.

Summary: A novel microwave absorbing material, sodium cobaltates (Na0.78CoO2), with a lamellar structure, was synthesized and showed good electromagnetic attenuate property. The composite with 50 wt% Na0.78CoO2 and 50 wt% paraffin achieved a minimum reflection loss (RL) of around -51.7 dB at a frequency of 8.2 GHz when the thickness was about 2.41 mm. Its effective absorbing bandwidths (RL <-10 dB) were in the range of 12.5 to 15.6 GHz for a sample thickness of around 1.5 mm. The electromagnetic attenuation mechanisms of the composite were related to conductive loss, multiple reflection loss, and dipole or interfacial polarization loss.

Summary: Surface plasmon resonance microscopy (SPRM) is widely used in biological fields for its high spatial resolution and label-free detection. In this study, a home-built SPRM system based on total internal reflection (TIR) was utilized to study the imaging of a single nanoparticle. By using a ring filter and deconvolution algorithm, the parabolic tail of the nanoparticle image was removed, achieving a spatial resolution of 248 nm. Additionally, specific binding between human IgG antigen and goat anti-human IgG antibody was successfully measured using TIR-based SPRM, demonstrating its capability in imaging sparse nanoparticles and monitoring biomolecular interactions.

Summary: This article presents an experimental investigation and optical modeling of structural coloration produced from total internal reflection interference within 3D microstructures. The iridescence generated for various microgeometries is modeled, examined, and rationalized using ray-tracing simulations, color visualization, and spectral analysis techniques. The observed iridescence is deconstructed into elementary components and linked to ray trajectories, which emanate from the illuminated microstructures. The findings provide a conceptual framework for understanding and tailoring the optical and iridescent properties of microstructured surfaces.

Summary: Spread spectrum time domain reflectometry (SSTDR) is used to test dielectric aging of a cable type used in the nuclear power plant industry. The data collected at 10-year intervals during the aging process showed a decrease in propagation velocity and characteristic impedance, indicating an increase in electrical permittivity as the cable aged. SSTDR proves to be a suitable method for monitoring and determining the aging of the cable.

Summary: A modified weak measurement scheme, rotatory biased weak measurement, is proposed to significantly improve the sensitivity and resolution of the total internal reflection sensor. The method introduces an additional phase in the post-selected procedure and generates an extinction point in the spectrum distribution. The performance of the sensor is analyzed, and an optimal refractive index resolution of 4 x 10(-7) RIU is demonstrated.

Summary: Imaging polarimetry methods have been proven effective in enhancing image contrast between tissues and structures in organic samples, and revealing structures hidden in regular intensity images. However, previous pseudo-colored images based on polarimetry were suboptimal. In this study, two new pseudo-colored methods based on Euclidean distances and likelihood for each pixel were proposed and experimentally validated on four different biological samples, demonstrating their potential in biomedical and botanical applications.

Summary: Chirality transfer from femtosecond laser direct writing in achiral transparent materials is caused by the interplay between anisotropic nanogratings and mechanical stress with non-parallel and non-perpendicular neutral axes. However, laser fabrication also induces significant linear birefringence. To precisely manipulate circular polarization properties and minimize linear birefringence, we propose a geometry-inspired multilayer method for direct writing of chiral waveplates. Theoretical analysis shows that our method achieves strong circular birefringence and provides a facile platform for chiral device exploration with minimal linear property existence.

Summary: In this study, vine leaves (Vitis vinifera) were investigated using imaging polarimetry at a wavelength of 530 nm. The aim was to demonstrate the potential of polarimetry and polarimetric microscopy for characterizing vegetal tissues, using vine leaves as a case study. The analysis of the Mueller matrix image of the sample revealed observables directly related to the sample's physical properties. Birefringence and dichroism were found to be useful markers for identifying specific structures in the sample, while polarimetric images enhanced contrast and allowed the visualization of previously invisible structures.

Summary: Polarimetry is an optical technique widely used in various fields, including biomedical research. It has been found that the polarimetric properties of biological samples, such as retardance, dichroism, and depolarization, can be measured to provide valuable information. This study focuses on investigating different depolarization metrics for biomedical applications and proposes the use of indices of polarimetric purity (IPPs) for biological tissue inspection. Results show that IPPs outperform the commonly used depolarization index, enhancing contrast between tissue structures and revealing hidden structures. Additionally, IPPs and other depolarizing observables demonstrate potential for accurate classification of different tissues.

Summary: This study reports the emission of polarized mid-wave infrared (MWIR) radiation from a 700 nm thick incandescent chiral metasurface. The polarization degree is above 0.5 with a circular polarization degree of 0.38 at 5 μm. The metasurface is heated by the Joule effect and the emission can be modulated beyond 10 MHz. This could enable detection techniques that use polarization as an additional degree of freedom.

Summary: Polarization manipulation is crucial for unlocking the versatility of light manufacturing, and existing techniques only focus on two-dimensional control. In this paper, we present a novel passive strategy using femtosecond laser written birefringent elements to shape polarization along the optical path. We demonstrate the generation of a three-dimensional structured Bessel beam with a slowly evolving polarization state, enabling the imprinting of twisted nanogratings and high optical rotation. Our work provides new perspectives on three-dimensional polarization manipulation and insights into applications in structured light and chiral device fabrication.
