Part one - instrumentation and measurements chapter I instrumentation and measurements

Two important and comprehensive books on the subject of dielectrics and dielectric measurements have been written by one of the foremost authorities in the field, Prof. von Hippel (1, 2). One book, entitled Dielectrics and Waves, is divided into two sections, one in which electromagnetic waves and their interaction with dielectric materials are thoroughly discussed, and another in which the molecular theory of dielectrics is very ably presented. This book is an invaluable reference source and will contribute significantly to the advancement of the art. The companion book, entitled Dielectric Materials and Applications, is primarily concerned with the measurement and application of dielectrics. An important feature of this book is the table of dielectric properties it contains. The properties of more than 600 dielectrics at frequencies between 100 cycles and 25,000 Mc and at various temperatures are tabulated. The book is based on lectures on dielectrics given by twenty-two experts at a Summer Session Course of the Laboratory for Insulation Research at the Massachusetts Institute of Technology in September 1952.
