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, …

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 …

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 …

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 …
