DEF

An instrument intended to measure the frequency of a periodic signal.

OBS

Several types of instruments are used as frequency meters in the various frequency bands. For power line frequencies(50-60 Hz), a simple vibrating reed instrument may be used. In radio frequencies, many instruments, such as wavemeters, use tunable resonant circuits, and in microwave frequencies, resonant cavities. Finally, digital frequency counters are useful over the whole frequency spectrum below infrared.

Record 5 2017-03-21

English

Subject field(s)
  • Advanced Technology Weapons
  • Radio Waves
  • Electronic Warfare
DEF

A type of DEW [directed-energy weapon] that uses RF [radio-frequency] energy to upset or damage the electronics of a target.

CONT

RF weapons are usually divided into two categories : high power microwave(HPM) weapons and ultrawideband(UWB)(or video pulse) weapons.

CONT

The primary distinction between RF weapons and more conventional EW systems is that RF weapons actually affect the electronics and not just the electronic environment, thereby causing temporary or permanent electronics failure that persists even after the RF beam has been turned off. RF weapons will mainly target receiver systems with in-band HPM [high-power microwave] radiation or computer systems with ultrawideband impulses.

CONT

In a radio-frequency weapon, electromagnetic radiation at wavelengths similar to that of radar is aimed at a target by means of an antenna. The principal effect would be to damage or destroy the electronic circuits of a missile.

La transmission d'énergie sans fil est conceptuellement semblable à la transmission d'informations à l'aide de satellites de télécommunications, mais elle est réalisée à une intensité plus élevée. Puisque le faisceau d'énergie est destiné à être converti en électricité à très haute efficacité, il serait possible de transmettre des quantités utiles d'énergie à des intensités inférieures à celle de la lumière solaire. Les possibilités de la transmission sans fil ont été démontrées jusqu'à un niveau de 30 kW sur de courtes distances (1,6 km), avec un rendement de conversion de l'énergie radiofréquence en énergie électrique supérieur à 85 %.

CONT

Le TESF (transport d'énergie sans fil) [...] suppose trois opérations relativement simples : la conversion de l'électricité en ondes, la transmission de ces ondes et enfin leur reconversion en électricité après réception [...] Pour faire voyager l'électricité, il vaut mieux utiliser des micro-ondes, qui ont une longueur plus importante (environ 12 centimètres) et qui sont pratiquement insensibles aux perturbations atmosphériques. Dans le cas du transport d'énergie sans fil (TESF), l'électricité est transformée en un rayon de micro-ondes, similaire au rayon laser [...] mais invisible. Le faisceau est dirigé vers une antenne de réception, composée de milliers de radiopiles. [On peut] produire de l'électricité à partir des micro-ondes en redressant les courants produits dans une antenne avec une diode à haute fréquence, qui nous donne du courant continu. L'élément combinant une antenne haute fréquence et le composant redresseur s'appelle une radiopile. Chaque radiopile ne produit qu'un peu d'électricité, mais en en associant des dizaines, des milliers, des millions, on obtient à la sortie le nombre de gigawatts demandés.

Subject field(s)
  • Analytical Chemistry
CONT

A simple arrangement of two cavities in series showed the feasibility of detecting traces of one gas in another. A klystron was used to generate microwave power which was fed through a wave guide to a transmission-type cavity. Another cavity was mounted in series with and tuned to the same frequency as the first; both cavities were identical except that the second had a gas inlet and outlet ports. From this measuring cell, its microwave energy was sent to a crystal detector. By frequency-modulating the klystron with a 50-cps sine wave voltage on the repeller, a burst of energy passes to the detector each time the generator frequency equals that of the cavities. The detector current is amplified and measured with an oscilloscope. At the beginning of the run, the two cavities are filled with the nitrogen carrier gas and, if the composition in one of the cavities is changed, its electrical size will change... causing a decrease of current from the detector.
