Reflection can significantly improve the quality of subwavelength near-field images, which is explained by appropriate interference between forward and reflected waves. Plasmonic slabs may form approximate super-mirrors. This paper develops general theory in both spectral and spatial representations that allows the re…

When more than two kinds of mobile ions are mixed in ionic conducting glasses and crystals, there is a non-linear decrease of the transport coefficients of either type of ion. This phenomenon is known as the mixed mobile ion effect or Mixed Alkali Effect (MAE), and remains an unsolved problem. We use molecular dynamic…

Highly ordered films were prepared by spreading out carbon disulfide (CS) solutions of ionomers over inorganic surfaces and for the first time over an organic surface. These ionomers, hydrophobic homopolymers or copolymers end-capped by a cationic group, were easily synthesized in a one-step reaction by a control radi…
