Seeing Through Concrete Walls With Waves
Seeing through 8 inch concrete walls is not impossible anymore , with this new machine the creators from Mit’s Lincoln Laboratories are able to detect people behind as much as 8 inch solid concrete walls making it very useful for any law enforcement personnel and other industries.
A microwave wavelength is used to radiate a signal wherever is needed such as a concrete wall where it would’ve been impossible before to detect life forms.
the microwave can detect energy behind the concrete the it can only transfer the 94.5 percent of the energy back to the antennas.
You will see on the video it is better explained of what this system does and how it works.
