For introductory Electrostatics I'd highly recommend Berkeley Physics Course Vol.2. For a graduate level treatment look at Classical Electrodynamics by Jackson. For electrostatic MEMS actuators do a Google search. Roger Shile -----Original Message----- I'm looking for a good resource on electrostatics in general, and on electrostatic actuation of MEMS devices in particular. Can any of you recommend a website (other than Wikipedia - I've looked there already) or text/handbook that covers the subject in some detail? Thanks, Brian Stahl
