An antenna is a device used to propagate, receive, and/or transmit electromagnetic waves which can have information embedded within them. The antenna creates an electromagnetic wave that carries the original embedded sound information through the atmosphere/space around it. An antenna at a different location, receives the electromagnetic wave, sending it …

Space-division multiplexing (SDM) has recently attracted great attention as a promising technology to further improve the transmission capacity and spectral efficiency. Very recently, SDM employing twisted lights, also known as orbital angular momentum (OAM) carrying lights, provides an alternative approach to increasing the transmission capacity and spectral efficiency of optical communications. …

Nanotechnologies involve designing and producing objects or structures at a very small scale, on the level of 100 nanometres (100 millionth of a millimetre) or less.  It allows humans to play with the building blocks of the universe, exploiting the laws of quantum mechanics to construct materials with unimaginable precision – …

The rapid increase in global energy consumption and the environmental impact of traditional energy resources pose serious challenges to human health, energy security, and the environment; and reveal a growing need to develop new types of clean and sustainable energy solutions  such as electric vehicles with low exhaust emissions. However the …

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. They are predicted to be able to protect the building from earthquakes by bending …

Nanomaterials (NMs) have gained prominence in technological advancements due to their tunable physical, chemical and biological properties with enhanced performance over their bulk counterparts. NMs are categorized depending on their size, composition, shape, and origin. Newly discovered materials such as fullerene, carbon nanotubes (CNTs), graphene, transition metal dichalcogenides, hexagonal boron nitride …

Every action our body performs begins with a thought, and with every thought comes an electrical signal. The electrical signals can be received by the brain-computer interface, consisting of an electroencephalograph (EEG) or an implanted electrode, which can then be translated, and then sent to the performing hardware to produce …

Metal–organic frameworks (MOFs) are periodic crystalline one-, two-, or three-dimensional structures composed of two major components: a metal ion or cluster of metal ions and an organic molecule called a linker. For this reason, the materials are often referred to as hybrid organic–inorganic materials. They are a subclass of coordination …

Quantum bits, or qubits, are the basic building blocks of quantum computers, just as bits are that of modern computers. Researchers around the world have been exploring a range of different physical systems to act as qubits, including trapping and isolating ions by using electromagnetic fields, photons trapped in microwave …

The world, say many experts, is on the verge of a second quantum revolution. The most talked-about of such technologies is the quantum computer, a device in theory so powerful that it could crack the codes underlying internet security in just a few minutes. But full-scale quantum computers are still …
