Electromagnetic waves in the millimeter-wave band (with frequencies between 30 and 300 GHz, or wavelengths between 10 and 1.0 mm) have attractive characteristics. One of their features is the wider usable frequency band compared with waves in the microwave band or lower bands. Another feature of using the millimeter-wave band is the fact …

Most AI advances and applications are based on a type of algorithm known as machine learning that finds and reapplies patterns in data. Deep learning, a powerful subset of machine learning, uses neural networks to find and amplify even the smallest patterns. Generative adversarial networks (GANs) are deep neural net …
Read More »Advances in Non Destructive Testing (NDT) and nondestructive evaluation (NDE) techniques for Aerospace and Military application
Non-destructive testing (NDT) is a way to detect and evaluate flaws in materials. The simplest and most accurate way of testing materials and components is often to test them to destruction. Destructive testing is used in aerospace to determine the physical properties of materials, components and assemblies. It can reveal …

Magneto resistor is a type of resistor whose resistance changes when an external magnetic field is applied. In other words, the flow of electric current through the magneto resistor changes when an external magnetic field is applied to it. Magnetic field is the region present around a magnetic object …
Read More »Rising employment of millimetre or EHF based radars, communications and seekers by Military creating new electronic warfare challenges
The advancement of Sensors, Communications and Radars have given rise to Electronic Warfare, which encompasses, in all battle phases, military actions involving the use of EM energy to determine, exploit, reduce or prevent hostile use of EM spectrum and the actions, which retain friendly use of the EM spectrum. The …
