This is the age of multidisciplinary frontiers in science and technology where major breakthroughs are likely to occur at the interfaces of disciplines. Light has always fascinated mankind and since the beginning of recorded history, it has been both a subject of research and a tool for the investigation …
Read More »Optical coatings are widely used in applications including architecture, consumer electronics, solar panels, automotive, medical, telecommunication, and military & defense. Optical or photonic coatings are generally used to increase the reflection, transmission, or polarization properties of a component, e.g., prisms, polarizing films, color filters, mirrors, diffraction mosaics, and refractory …
Read More »Metamaterials are artificial materials composed of periodic or aperiodic structures to have extraordinary electromagnetic characterizations. By properly tailoring the feature size of metamaterial, it can be realized electro-optic devices spanning the wavelength range from microwave, infrared (IR), visible to ultraviolet (UV) caused from the transformation optics. In view of …
Read More »Artificial Intelligence promises huge benefits to the world but lacks the proper infrastructure for implementation. AI infrastructure today is either too expensive, too slow, too hot or far too power hungry to be sustainable and commercially available to many potential customers. This is especially salient for edge solutions where accurate, …
Read More »Optronics, surveillance and sighting systems allow defence forces to effectively locate, track, observe and engage a range of targets in land, airborne and maritime warfare domains both during daylight and after dark. These military-grade systems play a vital role in border security, base protection, patrol and intelligence, surveillance and reconnaissance (ISR) missions. Unmanned systems have become an integral part of military forces worldwide, …

Phones and other GPS-enabled devices pinpoint your location on Earth by contacting at least four satellites bearing atomic clocks. Each of these satellites provides a time stamp, and the system calculates your location based on the relative differences among those times. The accuracy of GPS Navigation is primary degraded due …

Synchronizing modern electronic systems such as the Internet and GPS navigation is currently done using microwave atomic clocks that measure time based on the frequency of natural vibrations of cesium atoms. Those vibrations occur at microwave frequencies that can easily be used in electronic systems. Optical atomic clocks will …

Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation. There is a wide variety of photodetectors that may be classified by mechanism of detection, such as photoelectric or photochemical effects, or by various performance metrics, such as spectral response. Photodetectors are devices that measure photon flux or …

Currently, old-style personal Medicare techniques rely mostly on traditional methods, such as cumbersome tools and complicated processes, which can be time-consuming and inconvenient in some circumstances. Furthermore, such old methods need the use of heavy equipment, blood draws, and traditional bench-top testing procedures. Invasive ways of acquiring test samples can …
