DIELECTRIC BEHAVIOR OF LEAD NITRATE AND THALLIUM NITRATE AT WAVELENGTH OF ONE CENTIMETER
Abstract
The absorption of Pb(NO3)2 and TlNO3 in the frequency band 28-36 Gc was investigated. Instead of measuring the absorption directly, the dispersion of the real part of the complex dielectric constant is measured by slotted line methods. A graphical method of data analysis was developed for determining the dielectric constant of a low-loss, nonmagnetic material over a broad band of frequencies. This method of analysis is applied to the nitrate data. Values of dielectric constant versus frequency are plotted. The dielectric constant Pb(NO3)2 varied from 14.7 ! 0.1 to 14.4 ! 0.1 over the frequency band 28 to 36 Gc; the dielectric constant of TlNO3 was 13.5 ! 0.1 over the frequency band 27 to 37 Gc. Since dispersion is not exhibited by the real part of the dielectric constant, it was concluded that Pb-nitrate and Tl nitrate do not exhibit absorption in the frequency band 28 to 36 Gc. (Author)
