Propagation of Bessel beams in absorbing media: a new generation of GPR devices?

TL;DR

This paper investigates how Bessel beams propagate through absorbing layered media, providing insights that could enhance the development of advanced Ground Penetrating Radar (GPR) devices.

Contribution

It introduces a scalar analysis approach to model Bessel beam propagation in absorbing layered media, simplifying the complex vectorial analysis.

Findings

Bessel beams can penetrate absorbing layers with predictable behavior.

Scalar analysis effectively approximates vectorial field propagation.

Potential improvements for GPR device performance are suggested.

Abstract

The aim of this paper is the study of the propagation of a Bessel beam through two absorbing layers, limited by two different half-spaces. Our approach will be based on the scalar analysis, since this analysis was proved to be an excellent approximation of the vectorial field which describes a Bessel beam.
