Constellations of satellites are being proposed in large numbers; most of them are expected to be in orbit within the next decade. They will provide communication to unserved and underserved communities, enable global monitoring of Earth and enhance space observation. In a Low Earth Orbit (LEO), a satellite completes about …

Deployed electronic systems increasingly require advanced processing capabilities, however the time and power required to access system memory – commonly referred to as the “memory bottleneck” – takes a significant toll on their performance. Any substantial improvement in electronic system performance will require a radical reduction in memory access time …

Modelling is the process of representing a model (e.g., physical, mathematical, or logical representation of a system, entity, phenomenon, or process) which includes its construction and working. This model is similar to a real system, which helps the analyst predict the effect of changes to the system. Simulation of a …

Modern microelectronic semiconductors and integrated circuits provide remarkable computational and memory capabilities but lack the capability to interface with the physical world directly. MEMS (MicroElectroMechanical Systems) and the even smaller NEMS (Nano ElectroMechanical Systems) integrate sensors and actuators on microelectronic circuitry and enabling these products, awareness of the surroundings in …

Remote sensing is the science of acquiring information about the Earth’s surface without actually being in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Some examples of remote sensing are special cameras on satellites and airplanes taking …

Space is becoming more dynamic than ever with mega-constellations, multi-orbit satellites, and software-defined payloads. The world’s demand for broadband connectivity has created a new generation of high-throughput satellites in geosynchronous Earth orbit (GEO), medium Earth orbit (MEO), and now low Earth orbit (LEO). In the future, 5G networks will …

Carbon nanotubes (CNTs) are hollow cylindrical tubes formed by rolling a sheet of carbon atoms arranged in a hexagonal ring, as in a sheet of graphite, either in monolayer (single-walled nanotube, SWCNT) or multilayer (multi-walled nanotube, MWCNT) form. CNTs exhibit different electronic properties based on the way these graphene …
