#Electromagnetic Spectrum

[joehills]

I just hit a huge milestone designing my giant pinball machine in Minecraft: the playfield is all laid out!

I'm calling the game Deep Field, and there's five primary objectives based on hitting different shots representing bands of the electromagnetic spectrum.

IR: rollover switches Visible light: pop bumpers UV: captive ball X-rays: Drop targets Gamma rays: spinner

Also, a kinetic sling disc to light locks for Pluto Multiball!

Measuring Length: Transit-Time Measurements

One method of measuring distance, or length, is to emit a signal toward an object and measure the length of time it takes for that signal to return. Any signal can work for this method (sound, light, etc.), so long as the math for the speed of that signal is known (such as the speed of sound in water, or the speed of light in air, etc.). Then, a mathematical calculation can be performed to determine the distance between the signal emitter and the object.

Radar is one example of this method, using radio waves to determine distance. Another example is the global positioning system (GPS), which determines distance based on the time difference between your device and the signals sent from multiple satellites.

Figure 20.3 summarises the wavelengths and frequencies of some regions of the electromagnetic spectrum. (...) The infrared region of the electromagnetic spectrum (figure 20.3) covers the range of wavelengths from 7.8 × 10-⁷ m (just longer than the visible than the visible region) to 2.0 × 10-³ m (just shorter than the microwave region).

EM Waves in increasing order of frequency:

(source)

~~~

Radio Waves: Lowest frequency waves. Used to carry signals in communication industry.

Microwaves: Capable of penetrating obstacles and objects. Due to penetrating nature, they carry radar, computer data transmission etc.

Infrared Waves: IR waves of high wavelength - producing heat. IR waves of low wavelength - imaging technologies, remote controls. capturing pictures during fog, smoke etc.

Visible Light: Emitted by natural/artificial sources visible to the naked eye. (Objects are visible when they absorb light of specific wavelength and emit light of another wavelength)

Ultraviolet Waves: High frequency, low wavelength, used in studying molecular structures and help astronomers. Carcinogenic.

X-Rays: High energy waves (High frequency, low wavelength). View bone structures in the human body, X-ray therapy. Carcinogenic.

Gamma Rays: Used for medical purposes, cancer therapy. Also carcinogenic.

Researchers develop thermal radiation controllable epsilon-near-zero material that can withstand extreme environments

Thermal radiation is electromagnetic radiation emitted by all objects with temperature and most representatively, there is the solar radiation spectrum that enters the Earth and causes the greenhouse effect. Controlling and utilizing the thermal radiation energy emitted from solar power, thermal power generation, and residual heat in industrial sites can reduce the cost of electricity production. Therefore, interest in radiation spectrum controlling technology is increasing in areas such as cooling, heat dissipation, and energy production. Until now, radiation spectrum control technology has been mainly used in general environmental conditions, but recently, materials that can withstand extreme environments such as space, aviation and TPV system are needed.

HIMARS destroyed a modern Russian electronic warfare system - Technology Org

Electronic warfare systems do not fire shells, do not lay mines, do now launch missiles, but they can have devastating effects. Electronic warfare describes tools that basically work in the electromagnetic spectrum, jamming radio signals, disrupting communications, severing connections between unmanned systems and their operators and doing other dirty work. The Russian electronic warfare system RB-341B Leer-3 is an annoying thing like that and the defenders of Ukraine destroy them as soon as they find them.

The defenders of Ukraine managed to detect and destroy the Russian electronic warfare system RB-341B Leer-3. Ukrainian soldier Mykola Kolesnyk said that the valuable Russian system was spotted by drones of the 129th Separate Territorial Defense Brigade playfully called “Luftwaffe”. They determined the coordinates of the Leer-3 and tracked the device until the moment of destruction.

It only took one HIMARS missile to send this Leer-3 into Hell. But not only the electronic warfare system itself was eliminated. “The target was destroyed together with the operators,” said Mykola Kolesnyk. The crews of such systems are also extremely valuable targets, because they are highly trained professionals and that’s a finite resource.

The Leer-3 is a modern Russian electronic warfare and radio reconnaissance system operating in the GSM range. The Leer-3 has been in production since 2015.

The Leer-3 is capable of many different tasks. This system can suppress cell phone networks within a radius of about 6 km, send jamming signals and misleading messages, locate signal sources, and much more. The Leer-3 can identify locations with a high density of mobile devices and mark them as potential targets, because, of course, soldiers usually have many mobile devices.

This system can also act as an information transfer module, helping different units to coordinate their efforts and surveillance information. The Leer-3 is a bit of an unusual electronic warfare system, because it normally works with Orlan-10 drones. The Leer-3 crew normally consists of 5 people. It is mounted on the KamAZ-5350 6×6 chassis, so it can accelerate to 120 km/h and get ready for work in just 30 minutes after arriving at the designated place.

Ukraine is putting a lot of effort into destroying Russian electronic warfare systems, because they help the Russian invaders coordinate work between units, suppress Ukrainian communications, monitor mobile device gathering places, and disrupt the work of drones. Large electronic warfare systems are few and far between as they are expensive and their achievements are harder to sell to the policy makers than the work of artillery or missile systems.
