Response to Comment on `Undamped electrostatic plasma waves' [Phys. Plasmas 19, 092103 (2012)]

TL;DR

This paper presents numerical and experimental evidence supporting the existence of plateau states and corner modes in electrostatic plasma waves, offering a more accurate description of small amplitude disturbances than traditional models.

Contribution

It provides new experimental and numerical validation for plateau states and corner modes, challenging conventional plasma wave theories.

Findings

Evidence of plateau states and corner modes in plasma

Better description of small amplitude disturbances

Challenges to traditional wave models

Abstract

Numerical and experimental evidence is given for the occurrence of the plateau states and concomitant corner modes proposed in \cite{valentini12}. It is argued that these states provide a better description of reality for small amplitude off-dispersion disturbances than the conventional Bernstein-Greene-Kruskal or cnoidal states such as those proposed in \cite{comment}
