Query: Generalizing Elitzur-Vaidman interaction free measurements   In the early 1990's A. Elitzur and L. Vaidman proposed an interaction free
measurement (IFM) that allows researchers to find infinitely fragile objects
without destroying them. But Elitzur-Vaidman IFM has been used only to
determine the position of opaque objects. In this paper, we propose an
extension of such a technique that allows measurement of classical electric and
magnetic fields. Our main goal is to offer a framework for future
investigations about the role of the measurement processes, expanding the
physical properties that are measurable by means of IFM.
