Researchers at the University of Southampton, UK, have found a way to effectively shut down the current flow in graphene nanowires to produce a graphene channel transistor. Lead author Dr. Zakaria Moktadir tells us how.
Dr. Shahrzad Jalali Mazlouman, a researcher at Simon Fraser University, Canada, and author of the Letter Pattern reconfigurable square ring patch antenna actuated by hemispherical dielectric elastomer talks about her latest work on mechanically deformable antennas.
An electromagnetic crystal terahertz horn antenna, fabricated on a silicon substrate, has been developed by collaborating researchers from the University of Arizona and the Beijing Institute of Technology.
A novel ZnO nano-grating structure to enhance surface plasmon resonance (SPR) sensitivity is presented by researchers in Korea. The structure is intended to enhance the sensitivity of SPR optical biosensors, which convert biological interactions into measurable optical signals, providing information such as the presence of a specific biomolecule or the level of a biological pathogen in a medium.
Simultaneous transmission of broadband wired and wireless signals over 50 m of 1 mm-core graded-index plastic optical fibre (POF) is demonstrated for the first time in work from Italy and the Netherlands. POF could provide a less costly alternative to single-mode fibre, as a replacement for multiple current in-home network infrastructures, which deliver a widening range of in-home services.
To make simultaneous angle and corner detection possible, researchers from Korea have developed a new formula for the well-known Harris corner detector. The formula facilitates various analyses of the Harris corner and allows for a simple and fast method to calculate the angle of the detected corners without additional algorithms.
Establishing N-face GaN as an important candidate for future generation high-power microwave electronic devices, researchers from the US present the X-band power performance of N-face GaN MIS-HEMTs. Their results – very high efficiency and negligible dispersion – suggest the enormous potential of this new technology.
Researchers from France have derived a theorem for source coding, extending the Shannon theorem but with a new generalised coding length, lower bounded by the Tsallis entropy of non-extensive thermodynamics. Spanning the interface between information theory and statistical physics, their techniques will aid research into complex coding problems.
