The fact that sound can both heal and cripple, people have understood for a long time, but until recently this knowledge has hardly found practical application. Today, acoustic weapons are successfully used to disperse rallies and protect against pirates
The fact that sound can be a weapon, people have understood for a long time. From the earliest historical examples, one can recall the famous trumpets of Jericho, when, during the siege of Jerusalem, the troops of Joshua destroyed the walls with the sound of trumpets. The historical accuracy of this attack has not been confirmed, but the principle itself is important: the perception of a sound wave as a damaging factor.
The sound of a special frequency can not only cripple, but also heal. Today, it has been scientifically proven that bell ringing has a healing effect. When ringing at frequencies above 25 kHz, the shells of harmful microorganisms are destroyed, which is why they lose their destructive power. Bells do not like hepatitis and influenza viruses. However, not all viruses die from the bell ringing, only about 40%. In addition, in the zone of sound impact of the bell, due to a decrease in the hydrodynamic resistance of blood vessels, blood flow and lymph flow increase. In Russia, with the help of a bell, migraine and melancholy were treated. It was believed that the ringing of bells perfectly awakens a person after a sleepless night and sobers up after abusing strong drinks.
Directed energy weapons can be used stealthily ; radiation above and below the visible spectrum is invisible and does not generate sound.
Light (photons in the optical range) is practically unaffected by gravity, wind and the Coriolis force, which gives it an almost perfectly flat trajectory. This makes the sight much more accurate and extends the range to line-of-sight, limited only by diffraction and beam propagation (which reduces power and attenuates the effect), and by absorption or scattering by the atmosphere.
(DEW) have long attracted the attention of the military – and budgets – and are now on the cusp of technological maturity.
While doubts remain that certain types can be fully operational, recent testing of DEW prototypes has shown that this form of weaponry has gone beyond a purely theoretical concept.
As the underlying technology develops and is tested outside of laboratories, it is likely to attract increased attention from military and governments seeking to establish technical superiority over the enemy, including through the development of weapons that can be used in space.
At least several countries, including the US, China and Russia, have already announced these plans.
Notably, this definition excludes sonic and ultrasonic weapons, which use sound waves rather than electromagnetic waves to affect the target.
Therefore, we will be guided by the instructions of the “leader of the world proletariat”:
“Before uniting, and in order to unite, we must first strongly and definitely disengage.”
DEW currently exists in three main forms:
- lasers that can shoot down planes and missiles or use bright light to “blind” or disorient people;
- weapons using electromagnetic waves of other wavelengths, including millimeter waves or microwaves, which can be directed against people or technical targets;
- weapons that use particle beams to destroy or damage the target’s molecular or atomic structure.
High Power Microwaves (HPM)
Electromagnetic microwave weapons – the latest types of weapons, which are being worked on in the 21st century, disable the central nervous system, the brain, cause all sorts of unpleasant sensations, anxiety, despair, convulsions; interferes with the operation of computer systems, disables electronic equipment. It is intended mainly to control an aggressive crowd that commits illegal acts, and is also being developed as a weapon for the army.
Work on the creation of microwave weapons is being carried out in Austria, Germany, Great Britain, the USA, Sweden and other countries. Small dimensions, light weight (compactness) allow it to be used as a tactical weapon for offensive and defensive purposes. The development of personal portable weapons of this kind is also underway (work is underway on the creation of a stunner that transmits electricity via an ultraviolet beam at a distance of up to 2 km
Powerful microwave weapons use electricity to power a microwave generator that emits very short pulses—typically nanoseconds to microseconds long—of microwave radiation with an output power of megawatts to gigawatts.
Future HPM weapons could emit beams of radiation several degrees wide to attack targets in specific locations, or emit multidirectional radiation to destroy electronic components over wider areas.
The effects generated by HPM applications can range from the temporary disruption of electronic systems such as computers to the physical combustion of systems that are not shielded from the strong electromagnetic fields generated by the HPM pulse.
Because HPM beams cannot be focused as accurately as lasers, the energy per unit area in HPM beams decreases significantly with increasing distance. This can impose significant operational limitations compared to longer range laser weapons.
Since HPM weapons can affect all unshielded electronic systems within their beam, care must be taken when using them to avoid collateral damage to nearby friendly systems.
RF weapons release intense bursts of energy at microwave or lower frequencies that disable or destroy electronics. Such bursts can be caused by both nuclear and conventional explosives, but since these mechanisms result in omnidirectional, broadband bursts of energy, they cannot properly be called “directed” energy.
RF devices that produce directional energy typically resemble radar transmitters with steerable antennas to guide their beams. It can be argued that RF weapons, which transmit in all directions but at strictly limited frequencies, are a form of directed energy.
The viability of the HPM weapon.
Moisture in the air absorbs microwaves, and uncertainty about how electromagnetic energy travels through structures makes it difficult to predict how much damage an HPM weapon can cause. Also, countermeasures against high performance weapons can be as simple as surrounding sensitive electronics with a Faraday cage ( a pan on the head is also an option, though it’s safer to shield completely ).
A pulse that can affect electronic systems from a distance, the HPM weapon offers the ability to reduce collateral damage. Finally, the HPM weapon is inherently configurable, allowing the user to adjust the effects on the target.
Acute, unbearable pain causes a person to leave the microwave radiation area. No damage remains on the skin. Microwave emitters with a power of 1 GW (its weight is 20 kg) and more have been created (with a power of 20 GW, the weight of the apparatus reaches 180 kg). It is planned to equip artillery shells and cruise missiles with electromagnetic radiation generators.
