definition: "The presence of a thermal plasma in the emitting region means that the refractive index of the medium is less than unity and the phase velocity of electromagnetic waves is greater than $c$. As a result, synchrotron radiation is suppressed at frequencies where the refractive index becomes significantly less than 1. This is often called Tsytovich-Razin effect. The consequence is a low-frequency cutoff near
\begin{displaymath} \rm { {\nu_{R}} = {{4 c n e} \over {3 B_{\bot}}} = {{2\nu_{p... ... \nu_{0}}} \sim {{2 \times 10^{-5} n} \over {B_{\bot}}} MHz} \end{displaymath}" (string)
