Abstract

We predict that two electron beams can develop an instability when passing through a slab of left-handed media (LHM). This instability, which is inherent only for LHM, originates from the backward Cherenkov radiation and results in a self-modulation of the beams and radiation of electromagnetic waves. These waves leave the sample via the rear surface of the slab (the beam injection plane) and form two shifted bright circles centered at the beams. A simulated spectrum of radiation has well-separated lines on top of a broad continuous spectrum, which indicates dynamical chaos in the system. The radiation intensity and its spectrum can be controlled either by the beams' current or by the distance between the two beams.

Electromagnetic field of a moving charge in the presence of a left-handed medium

Journal Article Galyamin, Sergey; Tyukhtin, Andrey - Physical Review. B, Condensed Matter and Materials Physics

We analyze the electromagnetic field of a moving point charge in the presence of a 'left-handed' medium (LHM). First, the case of uniform motion of the charge in infinite LHM was considered. Using complex function theory methods, we decomposed the total field into a 'quasi-Coulomb' field, a wave field (Cherenkov radiation) and a 'plasma trace'. In addition, an effective numerical algorithm was developed for the total field computation, and typical plots were presented. It was shown that the wave field in LHM lags behind the charge more so than it does in ordinary medium. Furthermore, we investigated a charge intersectingmore »« less

Left-handed metamaterial design for Cerenkov radiation

Journal Article BaeIan, Wu; Jie, Lu; Kong, J; ... - Journal of Applied Physics

The design of a new type of left-handed material (LHM), having two dimensions of negative permittivities and one dimension of negative permeability, is presented in this paper for the observation and demonstration of the LH properties of Cerenkov radiation, which is a transverse magnetic (TM) electromagnetic wave. For a unit cell's dimension of 5 mm, a LH band is observed between 6 and 7 GHz upon a TM incidence. We also use an antenna array to model a traveling current source, representing a single frequency component of a moving charged particle, demonstrating the feasibility and basis of observing backward Cerenkovmore » radiation experimentally with LHM.« less

Left-Handed Structures for Accelerator Applications

Journal Article Antipov, S; Liu, W; Spentzouris, L; ... - AIP Conference Proceedings

Metamaterials are artificial periodic structures made of small elements and designed to obtain specific electromagnetic properties. As long as the periodicity and the size of the elements are much smaller than the wavelength of interest, an artificial structure can be described by a permittivity and permeability, just like natural materials. When the permittivity and permeability are simultaneously negative in some frequency range, the metamaterial is called double negative or left-handed and has some unusual properties. Left-handed metamaterials (LHM) have potential applications in active and passive devices at millimeter waves and at much higher frequencies. Waveguides loaded with metamaterials are ofmore »« less

Surface-wave mechanism of subwavelength imaging by a flat left-handed superlens

Journal Article Zharov, A; Noskov, R - Journal of Experimental and Theoretical Physics

We develop a theory describing the dynamics and interaction of electromagnetic surface waves (ESWs) resonantly excited by an external source in a slab of left-handed material (LHM) with identical negative (equal to -1) values of dielectric permittivity and magnetic permeability that makes up a so-called perfect lens, or a superlens. We show that subwavelength imaging by a superlens is associated with the degeneracy of the spectrum of eigen electromagnetic surface modes at the interfaces of the metamaterial slab, whereas the dynamic response of the superlens is completely determined by the dynamics of these modes and the dispersion properties of themore »« less
