Plasma wave resonance
= Plasma wave resonance
{title2=$n^2\to\infty$}
A limiting point of a <plasma> <wave> branch with divergent <refractive index>. At finite coefficients of the <magnetized cold-plasma dielectric tensor>, the generic condition is $S\sin^2\theta+P\cos^2\theta=0$. Poles of that <magnetized cold-plasma dielectric tensor> require a separate limiting analysis. <Collisions>, thermal dispersion or <mode conversion> can regularize a singular cold prediction.
