Improving Subwavelength Resolution of Multilayered Structures Containing Negative-permittivity Layers by Flatting the Transmission Curves
Multilayered structures consisting of alternating negativepermittivity and dielectric layers are explored to obtain high-resolution imaging of subwavelength objects. The peaks with the smallest |ky| (ky is the transverse wave vector) on the transmission curves, which come from the guided modes of the multilayered structures, can not be completely damped by material loss. This makes the amplitud...
متن کاملthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
15 صفحه اولMultilayered Superlenses Containing CsBr or Active Medium for Subwavelength Photolithography
The characteristics of periodic multilayered near-field superlenses are analyzed and optimized, using the dispersion relation derived from an effective medium theory and the transfer function in the spectral domain. The k′ z-kx and k′′ z -kx contours are used to explain and predict the spectral width, amplitude and phase of the transfer function. Superlenses containing CsBr or active layers are...
متن کاملResolution of subwavelength transmission devices formed by a wire medium.
The restrictions on the resolution of transmission devices formed by wire media (arrays of conductive cylinders) recently proposed in Phys. Rev. B 71, 193105 (2005) and experimentally tested in Phys. Rev. B 73, 033108 (2006) are studied in this paper using both analytical and numerical modeling. It is demonstrated that such transmission devices have subwavelength resolution that can in principl...
متن کاملexamining the relationship between fear of negative evaluation and communication strategies by iranian efl learners
the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
