When generated by a finite aperture of radius R≫2.4/kρR situated on the plane z=0, the solution in Eq. becomes a valid approximation only in the spatial region 0<z<R/tanθ≡Z and to ρ<(1−z/Z)R.

In this paper we use cylindrical coordinates (ρ,ϕ,z).

Fortunately, these conditions are satisfied for a great number of situations.

The same that was given in .

In an absorbing medium like this, at a distance of 25 cm, these beams would have their initial field intensity attenuated 148 times.

According to Eq. , the maximum value allowed for N is 158 and we choose to use N=20 just for simplicity. Of course, by using higher values of N we get better results.

The analytic calculation of these coefficients is quite simple in this case and their values are not listed here; we just use them in Eq. .

In this case, we can consider both ϵb(ω) and σ(ω) real quantities.

Notice that, according to Section , the absorption coefficient of a Bessel beam is αθ=αcosθ=2kIcosθ. When θ→0, the Bessel beam tends to a plane wave and αθ→α.

The idea developed in this section generalizes that exposed in Section 5 of , which was addressed to nonabsorbing media.

The same is valid for a truncated higher-order Bessel beam.

Notice that kρRm=N is the smallest value of all kρRm, therefore, if R≫2.4/kρRm=N→R≫2.4/kρRm for all m.

Here, θm is the axicon angle of the mth Bessel beam in Eq. .

That is, the shortest diffractionless distance is larger than the distance L.
