Summary: This paper confirms the transformation from spoof surface plasmon polaritons (SSPPs) to bound states in the continuum (BICs) by utilizing the metal plate array (MPA) and the ring dipole array structures. By broadening the aperture in the unit cell, the control of the skin depth of surface modes is numerically demonstrated while retaining the resonant frequency, and the fitting values of the plasmonic skin depth are in good agreement with theoretical values.

Summary: We propose a 1D reflective multi-level structural color design that combines Mie, plasmonic, and diffractive mechanisms in one pixel. By using a metallodielectric grating made of TiOx nanowires sandwiched between Ag thin film and Ag substrate, the design can display different color states depending on the polarization of incident light, either through Mie resonance or localized plasmonic resonance. The periodicity of the grating also allows for light diffraction, adding another color state. These results have implications in data encryption, anticounterfeiting, and data storage.

Summary: The magnetic response of natural materials is generally weak, especially in the optical range. Artificial magnetism is achieved through metamaterial design and the use of plasmonic nanostructures like split-ring resonators. These structures generate magnetic plasmons, which respond to external electromagnetic stimulation. The study of magnetic plasmons has become an active area of research in the past two decades, with various plasmonic nanostructures supporting magnetic plasmons. This Perspective reviews the latest studies, summarizes different nanostructures, discusses applications, and proposes future directions.

Summary: The proposed design involves all-dielectric isotropic micro- or nanoparticles that can provide negative effective electric permittivity and negative magnetic permeability when used as structural elements of a metamaterial. By adjusting parameters of three dielectric layers, the particles can excite electric and magnetic Mie dipole modes simultaneously. The isotropy of the particles suggests the potential use in a double-negative liquid metamaterial.

Summary: Flat optics nanogratings supported on thin free-standing membranes combine narrowband waveguided modes and Rayleigh anomalies for sensitive and tunable biosensing. Sharp waveguided modes and lattice resonances were achieved on high-refractive index Si3N4 membranes using lithographic nanogratings based on plasmonic nanostripes. These optical modes were fine-tuned over a broadband Visible and Near-Infrared spectrum, supporting strong near-field amplification and enabling versatile biosensing applications.

Summary: The study investigates the non-resonant mechanism of subwavelength imaging granted by a dielectric microsphere, confirming a hypothesis proposed previously. Numerical simulations demonstrate that the evolution of the phase front of the hollow wave beam formed by the microsphere enables deep subwavelength resolution of two dipole sources. The physical mechanism of imaging is not affected by the use of a 2D sphere in simulations instead of a 3D microsphere.

Summary: In this article, a novel omnidirectional wireless power transfer system based on double-toroidal helix coils is proposed and studied. The suggested antenna creates two mutually orthogonal magnetic fields through the double-helix coil wounded around a torus. The system consists of three transmitter-repeater pairs orthogonal to each other, ensuring omnidirectional functionality. Experimental results confirm self-tunability and high efficiency for any position and orientation of receivers.

Summary: The study demonstrates that deep subwavelength objects located on a dielectric substrate under a glass microcylinder show strong radial polarization, even under normally incident light. The cross-polarization effect arises due to the near-field coupling between the objects and the microcylinder, despite the tangential polarization of the incident electric field. This finding has implications for achieving super-resolution using a glass microsphere.

Summary: This paper suggests and studies a binary mechanism for long-distance image transfer in a wire-medium endoscope. The study shows that a discrete image formed by TM-polarized point sources with respect to the wire-medium can be transferred from the input to the output of the endoscope in a wide frequency range. The formation of local channels by adjacent wires allows the transfer of the near field beyond the Fabry-Perot resonances.

Summary: In conventional inductive wireless power devices, energy is transferred via reactive near fields, and radiation from transmitting and receiving coils is considered a parasitic effect that reduces power-transfer efficiency. This paper develops a dynamic theory of wireless power transfer between two small loop antennas, clarifies the role of far-field radiation, and proposes a possibility to achieve efficient wireless power transfer at large distances through radiation suppression. The analytical results are validated through simulations and measurements, offering the potential to greatly expand the distance range of compact wireless power-transfer devices.

Summary: Recently, there has been significant interest in reconfigurable intelligent surfaces (RISs) due to their potential for efficient and cost-effective wireless communication networks. However, the current modeling approaches often oversimplify the characteristics of RISs, neglecting important aspects such as resonant frequency dispersion and strong angular dependency of the reflection phases. In this paper, we address this challenge by studying a binary RIS and analytically examining the reflection phase frequency dispersion (RPFD). Our experimental results validate the accuracy of our numerical simulations and analytical predictions.

Summary: This work focuses on the electromagnetic properties of a resonator used to search for axions, a hypothetical candidate for explaining dark matter. By studying a wire medium loaded resonator, the authors found that the resonator's quality factor decreases as the volume increases, eventually being dominated by resistive losses in the wires. The experimental results confirm the theoretical findings, and even metals like copper can achieve higher quality factors than previously assumed.

Summary: In this paper, a third-order linear differential equation, named Rudenberg equation, is derived for describing polarization dynamics of a spherical plasmonic nanoparticle. The equation is analogous to the Abraham-Lorentz equation and was initially written in 1907 for elucidating the Hertzian dipole antenna in the receiving regime. Analytical solutions are found under certain assumptions to describe the radiative decay of the time-varying nanoparticle material.

Summary: In this paper, it is theoretically shown that a pair of plane waves impinging on a glass microcylinder under certain conditions may have a higher impact of evanescent waves, resulting in the suppression of the electromagnetic field in a specific area. This area, located in free space along the axis of the microcylinder, may serve as a linear optical trap for cold atoms and ions.
