HARMONIC RESONANCE, is my theory behind Frequency Discrimination,
Perhaps this partially explains why, and how Remote Sensing Discrimination (RSD, or MFD) works, and the energy "fields" hand held Antenna Rods & Directional Locators are reacting to. Dell
The answer the team came up with was
"resonance", a phenomenon that causes an object to vibrate when energy of a certain frequency is applied. This would work in a room let's say but you could adapt it to work in a factory
Marin Soljacic
"When you have two resonant objects of the same frequency they tend to couple very strongly," Professor Soljacic told the BBC News website.
Resonance can be seen in musical instruments for example.
"When you play a tune on one, then another instrument with the same acoustic resonance will pick up that tune, it will visibly vibrate," he said.
Instead of using acoustic vibrations, the team's system exploits the
resonance of electromagnetic waves. Electromagnetic radiation includes radio waves, infrared and X-rays. Typically, systems that use electromagnetic radiation, such as radio antennas, are not suitable for the efficient transfer of energy because they scatter energy in all directions, wasting large amounts of it into free space.
To overcome this problem, the team investigated a special class of "non-radiative" objects with so-called "long-lived resonances".
When energy is applied to these objects it remains bound to them, rather than escaping to space. "Tails" of energy, which can be many metres long, flicker over the surface.
"If you bring another resonant object with the same frequency close enough to these tails then it turns out that the energy can tunnel from one object to another," said Professor Soljacic.
Wireless energy transfer has been thought about for centuries
Hence, a simple copper antenna designed to have long-lived resonance could transfer energy to a laptop with its own antenna resonating at the same frequency. The computer would be truly wireless.
Any energy not diverted into a gadget or appliance is simply reabsorbed.
