Induced ultra-high frequency ultrasonic vibration as the driving force for reported sub-thermal microwave effects on materials

We examine a hypothesis that reported physical changes in certain materials resulting from their low-thermal exposure to intense GHz microwave radiation might be explained through generation of electromagnetically induced ultra high frequency ultrasound (hypersonic) waves within their structure. It can be shown from laws of electromagnetism that microwave fields should produce mechanical forces within dielectric, ferromagnetic, piezoelectric, and semiconductive materials and so give rise to high frequency acoustic vibrations. At the reported high power levels (100's to 1000's watts) of microwave at 2.45 GHz applied to materials, laws of acoustics suggest the generation of micron-order wavelength hypersound and possible particle accelerations greater than 10 ⁸ g. Consideration suggests that microwave-induced high intensity hypersound might account for reports of non-thermal disruption of material crystalline structure and apparent enhanced reactivity and diffusion effects.
