An Expansion Theorem for Electromagnetic Fields

A New Theorem Concerning Scattering of Electromagnetic Waves in Multilayered Metamaterial Spherical Structures

The proposed theorem in this paper is indicative of a kind of duality in the propagation of waves in the dual media of and in the spherical structures. Independent of wave frequency, the number of layers, their thickness, and the type of polarization, this theorem holds true in case of any change in any of these conditions. Theorem: Consider a plane wave incident on a multilayered spheric...

Negative reflections of electromagnetic waves in chiral media

We investigate the reflection properties of electromagnetic/optical waves in isotropic chiral media. When the chiral parameter is strong enough, we show that an unusual negative reflection occurs at the interface of the chiral medium and a perfectly conducting plane, where the incident wave and one of reflected eigenwaves lie in the same side of the boundary normal. Using such a property, we fu...

Exact Gaussian Beam Expansion of Time- Harmonic Electromagnetic Waves

The present contribution is concern with an exact framebased expansion of planar initial time-harmonic electromagnetic fields. The propagating field is described as a discrete superposition of tilted and shifted electromagnetic beam waveobjects over the frame spatial-spectral lattice. Explicit asymptotic expressions for the electromagnetic Gaussian beam propagators are obtained for the commonly...

Electromagnetic waves a new tool for cellular communications

Distant cells can communicate with each other in a variety of ways. Electrical and chemical mechanisms are two known mechanisms for the establishment of intercellular connections. In recent years, research has shown that many cells influence each other's behavior by sending electromagnetic waves together. The existence of such connections can justify many unknown cellular behaviors. The article...
