Introduction trends in dielectric research during i960

Continuing the trend of the past few years emphasis has been placed on the evaluation of complete insulating systems containing new combinations of known materials rather than on the application of new materials to the complex requirements of present-day insulation. Therefore, syntheses were based mainly on compound rather than molecular engineering. Much of the large volume of literature published, this year was of an essentially non-technical, semi-commercial nature but, at the same time some very sound theoretical work was done which should lead to a more basic understanding of the behavior of materials and the interdependence of their chemical, mechanical and electrical properties. This has required the development of more sophisticated measuring instruments and techniques. A few excellent, general reviews appeared which indicate the desire to establish fundamental understanding. As the field becomes more complex and more and more disciplines are involved it is becoming increasingly difficult to see the forest for the trees and these reviews should be especially helpful to new workers in the field. Toward this same goal many investigators have also been re-examining and extending earlier work.
