Query: Klein-Gordon Equation with Casimir Potential for Attosecond Laser Pulse
  Interaction with Matter   In this paper the Klein-Gordon equation (K-GE) is solved for the interaction
of attosecond laser pulses with medium in which Casimir force operates. It is
shown that for nanoscale structures, NEMS and MEMS, the attosecond laser pulses
can be used as the tool for the investigation of the role played by Casimir
force on the nanoscale. Key words: Casimir force; NEMS, MEMS, Attosecond laser
pulses.
