This paper deals with works on radar links in a three-dimensional marine environment. Radar performances prediction represents an important phase in the radar system parameterisation. This prediction is strongly related to the electromagnetic waves propagation modelling in maritime environment. The modelling of propagation, in troposphere, requires a good consideration of meteorological paramet...

Experiments are described on the prism-coupled excitation of surface electromagnetic waves in one-dimensional photonic band-gap arrays. The low loss of photonic band-gap materials leads to narrow angular reflectivity resonances and high surface fields. These attributes, coupled with the ability to engineer the optical properties of photonic band-gap arrays, suggest these materials as powerful r...

[1] A plane electromagnetic wave is incident at an oblique (skew) angle on a wedge of open angle 3p/2 with scalar face impedances, the same on both faces. When the theory previously developed for wedges of arbitrary angle with tensor face impedances is specialized to this case, the analysis simplifies, and the resulting expressions for the geometrical optics, surface wave and diffracted fields ...

In this study, we investigate the transparency of an overdense inhomogeneous plasma slab. This anomalous transmission is achieved when the conditions provided for the incident electromagnetic wave to excite coupled surface waves on the both sides of the slab. These conditions require that the homogeneous overdense plasma, or the metallic film, is placed between two dielectric layers. Here, the ...

A new wind-input and wind-breaking dissipation for phase-averaged spectral models of wind-generated surface waves is presented. Both are based on recent field observations in Lake George, New South Wales, Australia, at moderate-to-strong wind-wave conditions. The respective parameterizations are built on quantitative measurements and incorporate new observed physical features, which until very ...

voltages and currents are induced into electronic circuit boards as electromagnetic waves are radiated on them. the strength of induction depends on the wavefront and the circuit board characteristics. in this paper, by solving maxwell’s equations using fdtd method and then by extending it by three dimensional simulation using the gpml criteria for boundary conditions and tf/sf technique, effec...

We describe light scattering from a graphene sheet having a modulated optical conductivity. We show that such modulation enables the excitation of surface plasmon polaritons by an electromagnetic wave impinging at normal incidence. The resulting surface plasmon polaritons are responsible for a substantial increase of electromagnetic radiation absorption by the graphene sheet. The origin of the ...

It is shown that a smooth metal film (or a plasma layer) can be made transparent for an electromagnetic wave when two identical subwavelength diffraction gratings are placed on both sides of the film. The electromagnetic wave transmission through the metal film is caused by excitation of evanescent surface waves (plasmons) and their transformation into propagating waves at the gratings. A model...
