Instrumentation and measurement in the field of dielectrics

In the preparation of this report it has been difficult to segregate in the literature the components which fall within the scope of instrumentation and measurement. With no precedent as a guide, since the committee has not attempted in other years to divide the subject along the same lines, it has been necessary to choose the material rather arbitrarily. We have therefore looked first for new instrumentation, and second for new applications of previously existing instruments and methods of measurement. Papers which report data on measurements of properties of dielectrics, but which do not emphasize methods, are not discussed.
