From Fano-like Interference to Superscattering with Single Metallic Nanodisk
Superscattering was theoretically proposed to significantly enhance the scattering cross section of a subwavelength nanostructure, far exceeding its single-resonance limit by employing resonances of multiple plasmonic modes. By numerical simulation, we design a subwavelength nanodisk as a simple candidate to achieve superscattering. Due to the phase retardation, the subradiant mode can be excit...

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...

[ 5 ] Confi nement of plasmon modes to a surface of metal nanostructures under the constraints imposed by the fi nite boundaries of the nanostructure alters their dispersion, only allowing for discrete solutions. In the quasi-static limit, where the wavelength of the excitation light is much larger than the size of the nanostructure, the nan...
