SUMMARY:

In this dissertation, a brief study was made on the effects of stochastic radiation scattering by two gain and loss elevations and verification of the change in the frequency domain spectrum, i.e, the Wolf effect in both Hermitian and non-Hermitian configurations. We find analytically as frequencies where the spectral density of the scattered field disappears and we show that they are dependent on the gain and loss parameter. This demonstrates the non-Hermitian Wolf effect. Furthermore, the scattered radiation has a phase shift of π⁄2 and, also, there is a difference between the maxima and parameters in different configurations: Hermitian and non-Hermitian
