Vacuum Fluctuations and Casimir Forces

The Casimir force was predicated in 1948 by Dutch physicist H.Casimir,According to the theory of zero-point energy(ZPE) in Quantum Mechanics,when we consider two parrallel uncharged conducting plates,each mode of field contributes to a pressure on one plate and other,this experimentally confirmed small forces drawing the plates together.Since 1948,the Casimir forces still surprising after 62 years.The Casimir effect is very general and finds applications in various situation of physics.The theoretical and experimental results described here provide a deeper understanding of the phenomenon.The Casimir effect is one observable of the existence of the energy,i.e.the existence of electromagnetic field.The meaning of this word vacuum is physical-vacuum,not technology-vacuum.But,for the most precise measurement of the Casimir force between metallic surfaces,we propose that the experiment engage in technology-vacuum environment,such as the UHV field.
