Millimeter waves
NOV 01, 1950
Lying between the longest infrared rays and the shortest microwaves of the electromagnetic radiation is the region of millimeter waves, which are difficult to produce and to measure and which have as yet found few applications. The millimeter wave range, a relatively undeveloped field for research, presents a challenge to theoreticians, experimentalists, and inventors alike. This article was prepared at the request and through the cooperative effort of the ONRD advisory committee on millimeter wave generation as a means for stimulating effort in this new field.

Electromagnetic radiation, an inexhaustable natural resource, plays an extremely important part in modern technology and living. We use very short wavelength radiation, that is, x‐rays, in searching for otherwise hidden defects. We use longer wavelength radiation, that is, light, to see by. We can take photographs with infrared radiation. And all of these may be used through spectroscopy to identify substances and to study the structure of matter.
