The generation of concentrated energy of Bessel beams in an array of concentric rings
Daniela Mugnai
In recent years, the problem of the production of localized waves has been analyzed in various ways, from both a theoretical and a practical point of view. We present here a way in…
Propagation of Bessel beams from a dielectric to a conducting medium
D. Mugnai
Recently, the use of Bessel beams in evaluating the possibility of using them for a new generation of GPR (ground penetrating radar) systems has been considered. Therefore, an anal…
Propagation of Bessel beams in absorbing media: a new generation of GPR devices?
D. Mugnai, P. Spalla
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…
A short note on the propagation of a Bessel beam in conducting media
D. Mugnai
Recently, the use of Bessel beams in evaluating the possibility of using them for a new generation of GPR (ground penetrating radar) systems has been considered. Therefore, an anal…
Bessel-X waves: superluminal propagation and the Minkowski space-time
D. Mugnai
Superluminal behavior has been extensively studied in recent years, especially with regard to the topic of superluminality in the propagation of a signal. Particular interest has b…
Bessel beam propagation: Energy localization and velocity
D. Mugnai, I. Mochi
The propagation of a Bessel beam (or Bessel-X wave) is analyzed on the basis of a vectorial treatment. The electric and magnetic fields are obtained by considering a realistic situ…
Bessel beam through a dielectric slab at oblique incidence: the case of total reflection
D. Mugnai
The oblique incidence of a Bessel beam on a dielectric slab with refractive index n1 surrounded by a medium of a refractive index n>n1 may be studied simply by expanding the Bessel…
Tunneling time in the case of frustrated total reflection
D. Mugnai, A. Ranfagni, L. Ronchi
The tunneling time is here investigated by means of an electromagnetic model, for a system where a gap, between two parallel planes, acts as a classically-forbidden region for an i…
Passage of a Bessel beam through a classically forbidden region
D. Mugnai
The motion of an electromagnetic wave, through a classically-forbidden region, has recently attracted renewed interest because of its implication with regard to the theoretical and…
The tunnel effect in electromagnetic propagation
D. Mugnai
The tunnel effect is considered here within the framework of electromagnetic propagation. The classical problem of a plane gap of dielectric, surrounded on both sides by a medium w…
