  2. Microwave electrothermal thruster - Wikipedia

    en.wikipedia.org/wiki/Microwave_electrothermal...

    Microwave electrothermal thruster, also known as MET, is a propulsion device that converts microwave energy [1] (a type of electromagnetic radiation) into thermal (or heat) energy. These thrusters are predominantly used in spacecraft propulsion , more specifically to adjust the spacecraft’s position and orbit.

    On October 22, 2012, Boeing announced a successful test of the missile. [3] CHAMP disabled seven different targets before self-destructing over empty desert. [4] [5]The U.S. Air Force expected to have technology for a steerable counter-electronics weapon “available” in 2016, when a multi-shot, multi-target, high-power microwave (HPM) package would be tested aboard an AGM-86 ALCM.

  4. Microwave oven - Wikipedia

    en.wikipedia.org/wiki/Microwave_oven

    A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating .

    The sodium gas generated at the cathode then travels to a condenser at the heat-rejection temperature of perhaps 400–700 K, where liquid sodium reforms. The AMTEC thus is an electrochemical concentration cell , which converts the work generated by expansion of sodium vapor directly into electric power.

  6. Microwave - Wikipedia

    en.wikipedia.org/wiki/Microwave

    Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed.

  7. Monolithic microwave integrated circuit - Wikipedia

    en.wikipedia.org/wiki/Monolithic_microwave...

    Monolithic microwave integrated circuit, or MMIC (sometimes pronounced "mimic"), is a type of integrated circuit (IC) device that operates at microwave frequencies (300 MHz to 300 GHz). These devices typically perform functions such as microwave mixing , power amplification, low-noise amplification , and high-frequency switching.

  8. Directed-energy weapon - Wikipedia

    en.wikipedia.org/wiki/Directed-energy_weapon

    A weapon often described as an "anti-drone rifle" or "anti-drone gun" is a battery-powered electromagnetic pulse weapon held to an operator's shoulder, pointed at a flying target in a way similar to a rifle, and operated. While not a rifle or gun, it is so nicknamed as it is handled in the same way as a personal rifle.

  9. Gunn diode - Wikipedia

    en.wikipedia.org/wiki/Gunn_diode

    The negative differential resistance, combined with the timing properties of the intermediate layer, is responsible for the diode's largest use: in electronic oscillators at microwave frequencies and above. A microwave oscillator can be created simply by applying a DC voltage to bias the device into its negative resistance region. In effect ...
