TL;DR: A variety of configurations and formats have been devised to exploit the phenomenon of surface plasmon on metal dielectric interfaces for sensing a variety of significant analytes, such as pesticides and explosives, pathogens and toxins, and diseased tissue as discussed by the authors.
Abstract: A variety of configurations and formats have been devised to exploit the phenomenon of surface plasmon on metal dielectric interfaces for sensing a variety of significant analytes, such as pesticides and explosives, pathogens and toxins, and diseased tissue. Researchers continue to aim at detecting lower concentrations in smaller volumes of samples in real time. A new research field, called nanoplasmnonics, has emerged in this regard.

TL;DR: In this article, a uniaxial anisotropic perfectly matched layer (PML) absorbing material is presented for the truncation of finite-difference time-domain (FDTD) lattices for the simulation of electromagnetic fields in lossy and dispersive material media.
Abstract: A uniaxial anisotropic perfectly matched layer (PML) absorbing material is presented for the truncation of finite-difference time-domain (FDTD) lattices for the simulation of electromagnetic fields in lossy and dispersive material media. It is shown that by properly choosing the constitutive parameters of the uniaxial media both propagating and evanescent waves can be highly attenuated within the PML medium. This resolves the concern that the original Berenger's formulation for a PML medium does not attenuate evanescent waves. FDTD formulations for the uniaxial PML method are presented for lossy and dispersive medium. Based on this formulation an equivalent modified representation of Berenger's split equations is also derived. Through numerical examples, it is demonstrated that the uniaxial PML method provides a nearly reflectionless absorbing boundary for the FDTD simulation of evanescent and propagating waves encountered in highly dispersive and lossy medium.

TL;DR: In this paper, the differential form of the time-domain Maxwell's equations are first cast in a conservation form and then solved using a finite-volume discretization procedure derived from proven Computational Fluid Dynamics (CFD) methods.
Abstract: For computation of electromagnetic scattering from layered objects, the differential form of the time-domain Maxwell's equations are first cast in a conservation form and then solved using a finite-volume discretization procedure derived from proven Computational Fluid Dynamics (CFD) methods 1 . The formulation accounts for any variations in the material properties (time, space, and frequency dependent), and can handle thin resistive sheets and lossy coatings by positioning them at finite-volume cell boundaries. The time-domain approach handles both continuous wave (single frequency) and pulse (broadband frequency) incident excitation. Arbitrarily shaped objects are modeled by using a body-fitted coordinate transformation. For treatment of complex internal/external structures with many material layers, a multizone framework with ability to handle any type of zonal boundary conditions (perfectly conducting, flux through, zero flux, periodic, nonreflecting outer boundary, resistive card, and lossy ...

TL;DR: In this article, a modified finite volume method for solving Maxwell's equations in the time domain is presented, which allows the use of general nonorthogonal mixed-polyhedral grids, is a direct generalisation of the canonical staggered-grid finite difference method.
Abstract: A modified finite volume method for solving Maxwell's equations in the time-domain is presented. This method, which allows the use of general nonorthogonal mixed-polyhedral grids, is a direct generalisation of the canonical staggered-grid finite difference method. Employing mixed polyhedral cells, (hexahedral, tetrahedral, etc.) this method allows more accurate modeling of non-rectangular structures. The traditional “stair-stepped” boundary approximations associated with the orthogonal grid based finite difference methods ate avoided. Numerical results demonstrating the accuracy of this new method are presented.

TL;DR: In this article, the existence of surface waves in specific material examples is analyzed, discussing the challenge posed by their experimental observation, and the most important advances in this topic are briefly discussed in this review, pointing out aspects that have not been clearly covered by the literature.
Abstract: The interface of two semi-infinite media, where at least one of them is a birefringent crystal, supports a special type of surface wave that was predicted theoretically by D'yakonov in 1988. Since then, the properties of such waves, which exist in transparent media only under very special conditions, have been analyzed in different geometries and settings. Nevertheless, they are still awaiting experimental demonstration. The most important advances in this topic are briefly discussed in this review, pointing out aspects that have not been clearly covered by the literature. Finally, the existence of these surface waves in specific material examples is analyzed, discussing the challenge posed by their experimental observation.
