Surface polaritons of a left-handed material slab
The dispersion relations of the surface polaritons of a slab made of a material which has dispersive permittivity and permeability, and is left-handed over a frequency band in the microwave range of several GHz, are investigated. Four branches of p polarized surface polaritons and two branches of s polarized ones are found to exist. The possibility of experimentally observing the surface polari...
متن کاملEffects of Loss Factor on Plane Wave Propagation through a Left-Handed Material Slab
This article presents a theoretical and numerical discussion of the reflection and transmission analysis through a lossy left-handed material slab embedded between two semi-infinite dielectric media. The properties of the lossy left-handed material are given in detail and the required equations for the electromagnetic plane wave propagation are derived to solve the problem. The main important c...
متن کاملLeaky modes of a left-handed slab
Using complex plane analysis we show that left-handed slab may support either leaky slab waves, which are backward because of negative refraction, or leaky surface waves, which are backward or forward depending on the propagation direction of the surface wave itself. Moreover, there is a general connection between the reflection coefficient of the left-handed slab and the one of the correspondi...
متن کاملDesign of a composite right / left-handed slab-type material com- posed of multilayer metallic patterns
In this paper, a composite right/left-handed (CRLH) slab-type material excited by plane wave is proposed. It is composed of multilayer metallic patterns between dielectric substrates. The equivalent circuit is shown to design a balanced CRLH material. The balanced CRLH characteristics are measured. Next the CRLH material composed of four kinds of cells with different dispersion relation is desi...
متن کاملon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
