Ultrashort electromagnetic waves: I — Electromagnetic theory

Ultrashort electromagnetic waves are of vital importance at the present time. In keeping with the policy of the Institute to concentrate its efforts on matters closely related to the war effort, the basic science group of the AIEE New York Section is now presenting a series of lectures on this topic. The editor of “Electrical Engineering,” believing that this material should be made available to the entire AIEE membership, has asked the lecturers to prepare articles to be published in this journal. This first article lays the groundwork in fundamental theory for the entire series. Succeeding articles, all being prepared by recognized authorities, will cover: (II) transmission-line theory at ultrahigh frequencies; (III) generation; (IV) guided propagation; (V) radiation; (VI) reception. If sufficient interest is shown, a consolidated reprint will be made available after the full series has appeared. PAUL C.
