Abstract

The effects of source correlations on the radiated spectrum have been discussed in connection with scalar sources. We examine the spectrum of the field radiated by two linear dipoles that are partially correlated. The dipoles are assumed to be linearly polarized in the same direction and have identical spectra. Expressions are derived for the radiated spectrum, the total emitted power, and the directivity. We illustrate our results by calculating the radiated spectrum for some particular choices of the frequency-dependent correlation functions and by comparison with the well- known limiting cases of fully correlated and uncorrelated dipoles.
