Plasmonic Fano resonances have recently attracted a great deal of research interest due to their sharp asymmetric profile, high sensitivity the ambient material and low radiation damping. In this paper, we extend plasmonic that resulted from interference between bright dark modes in coreshell nanoparticle system for novel biosensing, optical switching applications, by using theory transformatio...

The past decade has seen a revolution in electromagnetics due to the development of metamaterials. These artificial composites have been fashioned to exhibit exotic effects such as a negative index of refraction. However, the full potential of metamaterial devices has only been hinted at. By combining metamaterials with transformation optics (TO), researchers have demonstrated an invisibility c...

Rotational transformation based on coordinate rotation in Fourier space is a useful technique for simulating wave field propagation between nonparallel planes. This technique is characterized by fast computation because the transformation only requires executing a fast Fourier transform twice and a single interpolation. It is proved that the formula of the rotational transformation mathematical...

In this paper the Laguerre geometry of three-dimensional Galilei space, that is, the geometry of oriented planes and cycles of an aane Cayley-Klein space with absolute line and two conjugate complex absolute points on it, is studied. Several diierent models are presented: A cyclographic model and an isotropic model together with their duals and an interpretation in terms of geometrical optics o...

A simple optical lens plays an important role for exploring the microscopic world in science and technology by refracting light with tailored spatially varying refractive indices. Recent advancements in nanotechnology enable novel lenses, such as, superlens and hyperlens, with sub-wavelength resolution capabilities by specially designed materials' refractive indices with meta-materials and tran...
