As I mentioned previous "Radiology". The use of radio frequency can alter the electromagnetic field of atoms/molecules, this causes a weird effect which has been notibly coined "The Hutchison Effect" by a freelance physicist that was interested in generating cheap power through radio frequency, however his experiments had "weird side effects".
As you should note, Radiology means the usage of Radio transmittion equipment from either or both ground arrays and satellites. The "Matricing" of the wavelengths must of course be computed which I gather would mean computing with systems located at each node in a network, which would allow something like a computer CAD package (The sort for drawing Mechanical designs) to control how the "Matricing" would effect a corn field.
This is where I mentioned "Gene-Therapy", which uses radiology to manipulate the very gene structures of DNA. It's been attempted by the medical profession within hospitals on guineapig patients and the results have been far from good.
[I did wonder if the plan was to create a mass clandestine Gene-therapy system the country over to try and defeat Cancers from smoking, obesity perhaps even germ warfare but all without the public knowledge, which could potentially place the public at risk since it means there is no publicised VETING of staff that run the equipment (They could have Murder, Rapist or Paedophile tendancies) and any deaths would be treated because of the secrecy as "Natural causes"].
If you had the capacity to Matrice radiology and your intension was to interact with genetic code at potentially string level (small than atomics), then Corn would be the first starting point since it's not a live test subject that could scream from pain or die from being operated on wrongly. This is why I suggest it's also proof that mind control equipment exists in how the corn genes are interacted at this microscopic level since to interface with the human brain at a communication level it would require the same capabilities.
