Abstract

ALL those who have been in any way connected with the vast developments in radio and radar techniques during the past decade will be familiar with the extensive contributions made during the war years by the staff of the Radiation Laboratory of the Massachusetts Institute of Technology. Much of the basic scientific and engineering knowledge which resulted from these contributions has been collected together by an editorial staff Working under the auspices of the United States National Defense Research Committee and is now being published in a series of volumes which has become familiarly known in the radio world as the ‘five-foot shelf'. The general design and scope of this publication, and details of the introductory volume to the series, have already been described in Nature (June 5, p. 867). The present review is concerned with Vols. 2, 3 and 4 of the series, which together add another three inches to the shelf.
