A theory is presented for the dispersion relations of the nonlinear phonon-polaritons arising when phonons are coupled to the electromagnetic waves in multilayered structures of nonlinear materials. The calculations are applied to a multilayered structure consisting of a thin film surrounded by semi-infinite bounding media where each layer may have a frequency dependent dielectric function and ...

Vectorial relations of field amplitudes are derived from the Lorentz lemma applied to electromagnetic fields at direct and reversed scenarios of a wave diffraction on a doubly-periodic planar array. Biorthogonality of polarization eigenstates of the waves propagating in opposite directions is shown with reference to a wave channel formed by an incident wave and a diffraction order. For a planar...

Chiral and bianisotropic metamaterials, where coupling of magnetic and electric phenomena plays an important role, offer advanced possibilities for the control and manipulation of electromagnetic waves. Such a control is particularly useful in the THz and far-IR region where natural materials do not show strong response and thus they are not offered as components for a direct realization of ele...

Suspended particles in the atmosphere during sand and dust storms have numerous consequences on electromagnetic wave propagation in arid regions. The electromagnetic wave signal may suffer attenuation and cross polarization upon encounter with the suspended particles. However, meager information has hitherto been reported about effect of storms on the telecommunication systems operating in such...

We demonstrate the utility of three-dimensional 3D optical Wannier functions WF’s for quantitative description of electromagnetic wave localization and propagation in 3D photonic band gap PBG microcircuits. Using these localized “optical orbitals” we reconstruct electromagnetic waveguiding in bulk twodimensional 2D and 3D PBG materials, 2D-3D PBG heterostructures composed of 3D PBG structures i...

A metamaterial electromagnetic wave absorber consisting of a big circular ring patch with four smaller suppression circular rings is presented in this report. The metamaterial electromagnetic wave absorber introduces the concept of size reduction by suppressing the resonance frequency. An FR4 substrate was used and the incidental wave angles were varied from 0 0 to 60 0 . Simulations results sh...

Discuss the scattering of a plane electromagnetic wave of angular frequency ω that is incident on a perfectly conducting sphere of radius a, which is at rest, when the wavelength obeys λ a (ka 1). Calculate the electromagnetic fields and the Poynting vector everywhere, and interpret these fields in both the near and far zones. Consider incident electromagnetic waves of both linear and circular ...

In this paper, we review our recent efforts in employing anisotropic metamaterials to manipulate electromagnetic wave polarizations, including conversions between different polarization states and rotations of polarization direction, in frequency domains ranging from microwave to visible. We first present a general theoretical analysis on the problem, and then discuss our experimental efforts i...
