Resonant excitation of surface plasmons in one-dimensional metallic grating structures at microwave frequencies
(Institute of Physics Publishing, 2005)Grating-coupling phenomena between surface plasmons and electromagnetic waves were studied in the microwave spectrum using metallic gratings. Transmission measurements were carried out to observe the transmitted radiation ... -
Rounding corners of nano-square patches for multispectral plasmonic metamaterial absorbers
(OSA - The Optical Society, 2015)Multispectral metamaterial absorbers based on metal-insulatormetal nano-square patch resonators are studied here. For a geometry consisting of perfectly nano-square patches and vertical sidewalls, double resonances in the ... -
A synthetic aperture imaging system using surface wave modes
(IEEE, 1995)A synthetic aperture acoustic imaging system with a novel inversion algorithm is described. Data is obtained by using a transducer insonifying the sample surface at a critical angle which is excited by a short electrical ... -
Theoretical investigation of excited states of oligothiophene anions
(2008)Electron-hole symmetry upon p- and n-doping of conducting organic polymers is rationalized with Hückel theory by the presence of symmetrically located intragap states. Since density functional theory (DFT) predicts very ... -
Tkachenko modes of the square vortex lattice in a two-component Bose-Einstein condensate
(2006)We study Tkachenko modes of the square vortex lattice of a two-component Bose-Einstein condensate (BEC) in the mean-field quantum Hall regime, considering the coupling of these modes with density excitations. We derive the ...
