We look at four length scales associated with the surface plasmon–polariton (SPP) modes in
the visible and near-infrared. We examine some of the consequences of these length scales
for exploiting surface plasmon–polariton modes as a means to provide sub-wavelength …

We discuss the optical transport properties of complex photonic structures ranging from
ordered photonic crystals to disordered strongly-scattering materials, with particular focus on
the intermediate regime between complete order and disorder. We start by giving an …

The speed of optoelectronic devices is normally limited by the components used on the
electronic side of the device. The direct generation of short light pulses from short current
pulses, for example, is limited by the speed of an electronic pulse generator or the response …

A new kind of tridimensional scalar optical beams is introduced. These beams are called
Lorentz beams because the form of their transverse pattern in the source plane is the
product of two independent Lorentz functions. A closed-form expression of free-space …

Morphodynamical predictive simulations of estuarine sediments require in situ mud floc data
for model verification and calibration purposes. The limiting factor in many previous studies
were the devices used for sampling, as flocs are very fragile. Instruments such as Niskin …

We review publications on transverse dynamics in cavity nonlinear optics during the years
2000–2003. Topics covered are transverse pattern dynamics, localized structures, scaling of
turn-on transients, properties of nonlinear PDEs, VCSELs, quadratic media, light valves with …

The author proposes the methodology of transformation optics in orthogonal coordinates,
which can obtain the material parameters of the transformation media from the mapping in
orthogonal coordinates. Several examples are given to show the applications of such a …

Hydrogen sensing at low concentrations in the order of tens to hundreds of parts per million
(ppm) over extended periods requires highly sensitive and stable sensor technology.
Palladium and its alloys are widely used in hydrogen sensing as they show a high and …

Energy trajectories, that is, integral curves of the Poynting (current) vector, are calculated for
scalar Bessel and Laguerre–Gauss beams carrying orbital angular momentum. The
trajectories for the exact waves are helices, winding on cylinders for Bessel beams and …

Seventy five years ago, three remarkable papers by Schrödinger, Kennard and Darwin were
published. They were devoted to the evolution of Gaussian wave packets for an oscillator, a
free particle and a particle moving in uniform constant electric and magnetic fields. From the …
