Summary: This work achieves frequency-dependent characteristic impedance extraction and compact excitation of spoof surface plasmon polariton (SSPP) waveguides. By investigating the near-field distribution of a typical SSPP waveguide, a special excitation position is found, allowing for transition between microstrip and SSPP waveguides in desired frequency bands. The proposed method offers a more compact size and better transition performance compared to conventional strategies, and is not impacted by internal discontinuities and local couplings.

Summary: A three-point finite difference method with an arbitrary order of accuracy is proposed for the modal analysis of chiral planar waveguides. This method utilizes a nonuniform grid, compact finite difference technique, and boundary conditions to efficiently analyze waveguides with a discontinuous profile of permittivity, permeability, and chirality.

Summary: This article presents the investigation and design of high-performance transitions from coplanar waveguide to single-conductor, corrugated waveguides for terahertz spoof surface plasmon polariton waveguides. A novel methodology is proposed to examine the relationship between guided wavenumber and momentum matching, allowing for the design of low-loss transition circuits.

Summary: To reduce transversal width, a new spoof surface plasmon polariton (SSPP) based on coplanar waveguide (CPW) is proposed. By using capacitor loading technique to control the dispersion characteristics and electromagnetic field, the proposed capacitor-loaded CPW SSPP exhibit a similar transmission performance to conventional unloaded CPW SSPP TL, but with a transversal width reduction up to 64%. On this basis, another modified capacitor-loaded CPW SSPP is presented by changing the groove shape from strip-shape to T-shape. Results validate that the transversal width of the T-shape CPW SSPP is only 24% to that of conventional unloaded CPW SSPP. Besides, much more tighter field confinement is achieved for both the two proposed CPW SSPPs. Such results are of great significance to reduce the size of plasmon devices in microwave regime.

Summary: This study investigates the emission of surface polaritons (SPs) by a charged particle moving inside a dielectric cylinder parallel to its axis. It is found that the SP modes exist for the positive dielectric function of the cylinder material. The electromagnetic fields corresponding to SPs are determined and their properties are analyzed. The relativistic effects can significantly increase the radiated energy and affect the confinement region and frequency range of the radiated SPs.

Summary: In this study, a novel strategy is proposed to manipulate the switching and slow wave features of spoof surface plasmon polaritons (SPPs) based on plasmon-induced transparency (PIT) spectral responses. The strategy involves loading a combined module of split square-ring resonators and electric-LC resonators into the SPP waveguide to achieve a high modulation contrast in SPP transmission at the PIT peak frequency.

Summary: The study demonstrates control over the spatial and temporal properties of surface plasmon polaritons (SPPs) launched from nanohole arrays in silver, showing that SPPs launched from multiple arrays can interfere at defined spatial positions to form an all-SPP periodic nano-optical grating that evolves as the SPPs propagate. The spatio-temporal characteristics of the optical grating can be tuned through various nanohole array parameters, and the temporal interference of SPPs with different central wavelengths can be tailored through multiperiodic arrays (MPAs) consisting of arrays with different pitches placed adjacent to one another. Temporal interference serves as an encoded signal, where frequency components can be controlled by array properties.

Summary: This paper describes a new ISPRi technique for real-time monitoring of biomolecule binding on sensor surfaces through the interrogation of the differential value of two intensities at two specific wavelengths from the reflected light spectrum. By optimizing the selection of dual-wavelength parameters under different circumstances, the technique achieved a refractive index resolution (RIR) of 2.24 x 10(-6) RIU, surpassing traditional ISPRi techniques and enabling real-time detection of high-throughput biomolecular binding. This study is expected to advance the development of faster and more accurate SPRi technologies.

Summary: The study focuses on the polaritonic bandstructure of a 2D atomic lattice coupled to a surface plasmon polariton mode in the single excitation regime. By using a computational technique based on Dirichlet-to-Neumann map, a 2D atomic lattice is designed using only two-level atoms with an isolated flat polaritonic band where the group velocity for the modes approach zero across the Brillouin zone. Such a system could be utilized for slowing, storing, and manipulating single photons in a 2D geometry.

Summary: The report investigates the statistical temporal distribution of nonlinear upconverted photoluminescence emitted by gold and silver nanostructures excited by focused near-infrared laser pulses. Regardless of the nano-object's geometry, material's crystalline arrangement, and electronic band structure, a clear signature of photon bunching is systematically observed. The correlation of photons at a picosecond time scale released by nanoscale nonlinear sources of broadband radiation may be used in developing new data processing functionalities in plasmonic devices.

Summary: This research demonstrates that plasmonic nanowire-nanoparticle systems can perform nonlinear wavelength and modal conversions, potentially serving as building blocks for signal multiplexing and novel trafficking modalities.The generation of a localized broadband nonlinear continuum in the nanowire surface as well as at active locations defined by sites where nanoparticles are absorbed may couple to new sets of propagating modes enabling a complex routing of optical signals through modal and spectral conversions. Various aspects influencing the optical signal conversions are presented, including parameters defining the local formation of the continuum and the subsequent modal routing in the nanowire.
