Cluster bombs (also known as Cluster munitions) are a type of weapons that open in mid-air and disperse smaller submunitions— anywhere from a few dozen to hundreds—into an area. It can be explosive, chemical or biological in nature. They can be delivered by aircraft or from ground systems such as artillery, …
Read More »Terahertz (THz) represents the portion of the electromagnetic radiation between the microwave and the infrared region. It is within the frequency range of 0.1–10 THz, corresponding to wavelengths of radiation from 3000 to 30 µm. The advantages of the terahertz light are that they are non-invasive, intrinsically safe, and non-ionizing, …
Read More »A thermobaric weapon (also known as an aerosol bomb or Fuel Air Explosive) is a type of weapon the used the oxygen in the surrounding environment to generate a high-temperature explosion. While conventional explosive weapons are 25% fuel and 75% oxidizer, Thermobaric weapons consist of 100%fuel and as a result, are …

Bluetooth, developed in the late 1990s, is a technology designed to enable short-range wireless communication between electronic devices, such as between a laptop and a smartphone or between a computer and a television. Bluetooth works by using radio frequencies, rather than the infrared spectrum used by traditional remote controls. As …

Quantum computing and quantum information processing are next revolutionary technology expected to have immense impact. Quantum computers will be able to perform tasks too hard for even the most powerful conventional supercomputer and have a host of specific applications, from code-breaking and cyber security to medical diagnostics, big data analysis …
Read More »As a vessel travels under or on the surface of water, it causes a detectable local disturbance in Earth’s magnetic field. This disturbance, referred to as the magnetic signature, makes the vessel vulnerable to enemy defense systems. In submarine warfare, adversaries use increasingly sophisticated magnetic sensor and signal processing equipment to …

The United States depends on a variety of raw, non-fuel materials dubbed “critical minerals” to manufacture products considered essential to national security. These products can range from rare earth minerals in electric motors and generators, to the carbon fiber used for airplanes. Increasing demand, coupled with limited domestic supply and …
Read More »Currently, most vehicles rely on internal combustion engines for locomotion; however, a significant shift toward partial and complete electrification is likely to emerge as an alternative propulsion system for vehicles. An internal combustion engine system is highly cost-effective and hence, its usage is higher than other propulsion systems. Being a …

A submarine is a naval platform that can stay underwater for an extended period to carry out missions, both offensive and defensive. It is a complex platform that includes multiple components. As radio waves cannot propagate in water, communication with submarines is difficult. To overcome this issue, submarines are being …
