sheath theory

Sheath theory describes how energy propagates along wave-like structures called "sheaths" surrounding particles or fields, often in plasma physics or electromagnetic contexts. These sheaths act as boundary layers that influence how signals, particles, or energy move through a medium. Essentially, they serve as transitional zones that shape the behavior of waves and particles, affecting factors like speed, direction, and interaction. Understanding sheath theory helps scientists predict plasma behavior or improve technologies like controlled nuclear fusion, particle accelerators, and electromagnetic wave transmission by analyzing how these boundary layers impact overall system dynamics.
