Micro-opto-mechanical switching and tuning for integrated optical systems
… circuits would provide wavelength-selective switching. Wavelength- selective behavior is an important characteristic for devices intended for networking applications as wavelength division multiplexing (WDM) of optical signals has become the accepted standard. A major contribution of this …

First Principles Study Of Tribopolymerization On Conductive Material Surfaces
… used to lubricate and to protect the surfaces of mechanical gears, it is considered as a major source of contamination to Micro-electro-mechanical system and Nano-electro-mechanical system (MEMS and NEMS) transistors. MEMS and NEMS, analogous to atomic force microscopy (AFM) devices, design with …

Advancing 5G Coverage: Novel Methods for Metasurface Characterization and Leaky-Wave Antenna Reconfigurability
… limitations. Using numerical superposition and mechanical displacement, it creates user-defined incident fields, reducing design-measurement discrepancies. This facilitates improved MS deployment for 5G coverage. Inspired by source displacement, a pattern reconfigurable LWA design with …

Investigation of electrical, optical and mechanical control of ferroelectric domains using scanning probe microscopy
… understanding of electrical, optical and mechanical manipulation of ferroelectric domains in ((K0.5Na0.5)NbO3–2 mol% Ba(Ni0.5Nb0.5)O3−δ) (KNBNNO). KNBNNO is a novel bandgap (1.6 eV) engineered ferroelectric with an excellent piezo-response (100 pm/V). This made it interesting for …

Synthesis of linear copolymers and of polymer brushes substituted with spiropyran groups : a step towards light driven molecular walkers
… shifting and conversion of light energy into mechanical switching. These changes are based on the light induced isomerization of the usually non-polar spiropyran species to zwitterionic merocyanine species. Different well-defined linear copolymers, like P(MMA-co-HEMA), P(BA-grad-HEMA-TMS), …
