Montgomery C.G. (ed.) Technique of Microwave Measurements

New York: McGraw-Hill, 1947. — 939 p. — (MIT Radiation Laboratory Series. Volume 11)Most of the methods to be described are based on the wave character of high-frequency currents, rather than on the low-frequency techniques of direct determination of current or voltage. The techniques to be described are grouped under four main headings:
I. Power Generation and Measurement.
II. Wavelength and Frequency’ Measurements.
III. The Measurement of Impedance and Standing Waves.
IV. Attenuation and Radiation Measurements.
Parts I and 11 need no further comment except that the measurements peculiar to radiation from pulsed generators are included as Chap. 7 of Part II. The numerous bridge measurements, so important in the lowfrequency region, cannot be easily modified for microwave work, but analogous methods have been devised and show great promise for future development. These methods are discussed in Chap. 9 of Part III.
The inclusion of the measurements of dielectric constant in Part III is based on the fact that it is the dielectric constant which determines the intrinsic impedance of a medium, since the permeability of nearly all substances is very closely the same as that of a vacuum. Although attenuation and radiation measurements are essentially measurements of power, the special devicw employed make it convenient to consider such measurements in a separate part.
