Spintronics is an emerging field of nanoscale electronics whose central theme is the active manipulation of spin degrees of freedom of charge carriers in solid-state systems, in addition to their electronic charge used in traditional semiconductor electronics. Spintronics or spin electronics…
The threats of chemical, biological, radiological, nuclear and explosive (CBRNE) hazards continue to advance. CBRN weapons are some of the most indiscriminate and deadly weapons in existence today, with capability to affect large population in wide geographical area and in…
Modern cryptography being used extensively for securing our internet payments, banking transactions, emails and even phone conversations use cryptographic algorithms based on public-key encryption, which is considered to be secure against attacks from modern computers. The development of quantum…
Silicon carbide, also known as carborundum, is a unique compound of carbon and silicon and is one of the hardest available materials. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and…
Integrated circuits and power devices utilized by the semiconductor industry for the production of advanced computers, consumer electronics, communication networks, and industrial and military systems have been almost exclusively based on silicon technology. The requirements of future electronics place a…
The global race is now on to develop 5G, short for 5th generation mobile networking or 5th generation wireless systems which will change the face of the mobile communication . The Fifth Generation (5G) mobile networks will see the initial…
Geopolymer concrete—an innovative material in light of the ongoing emphasis on sustainability is a potential alternative to conventional portland cement concrete for use in transportation infrastructure construction. In contrast to portland cement, most geopolymer systems rely on minimally processed natural…
Military has become highly dependent on satellites for high data rate beyond line of sight communications as well as network centric operations. Satellite communications are also required to support military operations that are becoming more complex as conflict areas grow…
The quantum cascade laser is a special kind of semiconductor laser, usually emitting in the mid- and long-wave infrared bands. Such a laser operates on laser transitions not between different electronic bands but on intersubband transitions of a semiconductor structure. Their…
The fiber optic sensors also called as optical fiber sensors use optical fiber or sensing element. These Sensors can measure a large variety of parameters, such as temperature, pressure, strain, refractive index, vibrations, displacements, bending, loading, and liquid level or…
