Comment to the paper "Radiation induced by relativistic electrons propagating through random layered stacks: Numerical simulation results" by A.A.Varfolomeev and et al NIM B 256,705 (2007)

TL;DR

This paper critiques a previous study by demonstrating that its numerical simulation method inadequately accounts for multiple scattering effects, leading to incorrect results in modeling radiation from relativistic electrons in layered stacks.

Contribution

It provides a critical analysis showing the inadequacy of the numerical code used in the referenced paper for simulating electromagnetic scattering.

Findings

The original numerical code neglects multiple scattering effects.

The previous results are therefore unreliable due to this oversight.

Proper modeling requires accounting for multiple scattering effects.

Abstract

We show that the numerical code used in the above mentioned paper does not take into account the multiple scattering effects of electromagnetic field properly and is therefore incorrect.
