A favorite device for science fiction and action movie writers is the EMP generator. An EMP (or electromagnetic pulse) has the power to knock out all electronic devices within its range. Be careful because this could be dangerous. Supervise your kids if they want to try their hands at this....
The existence of a metal body which will conflict with coil L1's electromagnetic field is required for the object finder circuit to work. Both the inductance value of L1 and the frequency of the field are affected by the intruding object. A battery-powered portable broadcast band radio brought...
a 60 GHz signal propagating through air will suffer a significant spike in attenuation due to the electromagnetic absorption characteristics of oxygen. Often, 60 GHz radars have an effective range
It is believed that the applied electromagnetic field created in the pipe or duct carrying the beer interferes with the electron transport chain within the cell thus to inhibit uptake of nutrients, leading to cell stasis, or death. Additionally, the electromagnetic field may block uptake of a key...
This type of electromagnetic pulse generator works best for small electronics.[1] Using an EMP outside of your home or on any device owned by someone else is functionally illegal. Do not build an EMP device to use on others.[2] Warning: Do not use an EMP if you or anyone around ...
With that said, a 60 GHz signal propagating through air will suffer a significant spike in attenuation due to the electromagnetic absorption characteristics of oxygen. Often, 60 GHz radars have an effective range of less than 20 m. Angular Resolution The angular resolution of a radar is a ...
