We present a precise theoretical explanation and prediction of certain resonant peaks and dips in the electromagnetic transmission coefficient of periodically structured slabs in the presence of nonrobust guided slab modes. We also derive the leading asymptotic behavior of the related phenomenon of resonant enhancement near the guided mode. The theory applies to structures in which losses are n...

The launching of high-frequency electromagnetic waves into fusion plasmas is an effective method for plasma heating and noninductive current drive. In addition, the reflection of electromagnetic waves on the plasma cutoffs is utilized in electron density diagnostic measurements. The scope of this article is to comment on the standard approximations made in the simulation of electron-cyclotron w...

A comprehensive study of electromagnetic waves underwater propagation for a wireless sensor network is introduced in this paper. A mathematical model for the path loss due to attenuation of electromagnetic waves propagates in sea and pure water is given. Reflection from the air-water and water-sand interfaces as a function of distance between sensors and water depth is also introduced. A high g...

The geometric representation at a fixed frequency of the wave vector (or dispersion) surface omega(k) for lossless, homogeneous, dielectric-magnetic uniaxial materials is explored for the case when the elements of the relative permittivity and permeability tensors of the material can have any sign. Electromagnetic plane waves propagating inside the material can exhibit dispersion surfaces in th...

The scattering analysis from metallic Grid FSS consisting of rectangular perforations on a thick metallic screen illuminated by an oblique incident plane wave is presented. The grid structure is analyzed using Scale Changing Technique (SCT) which is based on the partition of the grid-plane into planar sub-domains defined at various scale-levels. Electromagnetic interaction between subsequent sc...

When a plane wave illuminates an electromagnetic band-gap (EBG) structure, the reflection phase continuously changes from 180° to -180° as the frequency increases. Especially at a certain frequency where the reflection phase is 0o, the surface shows the same property as a perfect magnetic conductor (PMC). The PMC material does not exist in nature, b u t an artificial magnetic conductor (AMC) ca...

Three-dimensional (3D) structures such as nanowires, nanotubes, and nanorods have the potential to increase surface area, reduce light reflection, and shorten charge carrier transport distances. The assembly of such structures thus holds great promise for enhancing photoelectrochemical solar cell efficiency. In this study, genetically modified Tobacco mosaic virus (TMV1cys) was used to form sel...

The boundary problem of linear classical optics about the interaction of electromagnetic radiation with a thin dielectric film has been solved under explicit consideration of its discrete structure. The main attention has been paid to the investigation of the near-zone optical response of dielectrics. The laws of reflection and refraction for discrete structures in the case of a regular atomic ...

We consider the symmetry in the interaction of photons and electrons, which has led to a common description of electron and photon accelerations; effects such as photon Landau damping arise naturally from such a treatment. Intense electromagnetic waves can act as a photon mirror to charged particles. The subsequent acceleration is equivalent to the photon pulse accelerating electrons. During th...

We present a theoretical approach that terahertz surface plasmon polaritons (THzSPPs) are tuned by temperature in a stack of dielectric and semiconductor with periodic corrugations. Based on Rayleigh hypothesis, we show that when THz electromagnetic wave illuminates the waved stack, temperature-dependent THz-SPPs are excited. At resonant modes, reflection dips or Fano-type resonance shape are f...
