We compare the experimental characteristics of the near field of transverse dynamic acoustic and EM fields. Grounding on the comparison, we conclude that in both dynamic fields the near region is separated into three sub-regions having the salient features inherent in both fields.

We establish that in the near of both fields the delay phase does not vanish but depends in a complex way on the distance from the source. With it in the second region of the near field, where the wave propagation velocity is minimal, the value of delay phase exceeds the related value for the far field.

This analysis fully lifts the contradiction between the properties of gas-like aether and those of transverse acoustic wave.

Keywords: Acoustics, radio waves propagation; near field of radiation; acoustic-electromagnetis analogy.

1. Introduction

The absence of full analogy between the wave propagation in elastic media without the shear deformation and EM waves is known to be the stumbling-block in constructing the consistent phenomenological model of the aether. When Maxwell derived his field equations, and Hertz after him, they actively used the laws of hydrodynamics. "We should mark that Maxwell stated his famous equations (20 totally) including 20 variables in his work 'Dynamic theory of electromagnetic field' (1864), and a number of his works collected as 'On Faraday's force lines' published in 1856, as well as 'On physical force lines' (1862) preceded it. As stated in the textbooks, Maxwell 'postulated' his equations, but factually Maxwell rigorously derived them, basing on the model of moving aether, in which the vortex tubes ('Faraday tubes') arise, using the data of vortex motion in liquids and grounding on the Helmholtz works, in which he considered the vortex motions of an ideal liquid, meaning it unviscose and uncompressible. Maxwell attributed the properties of ideal liquid to the aether, created the model of vortex motions of liquid aether, applied the Helmholtz theorems which said that the vortexes in an ideal liquid do not arise and annihilate but only move, and indicated that the vortex circulation along its axis is constant. In this way he connected all parameters of the moving liquid and obtained the equations of electrodynamics" [1, p. 118- 119].

At the same time, "in liquids and gases there does not exist the elastic resistance to the transverse shift of particles, but only to the volume variation, i.e., to the compression either rarefaction. So in such substances only longitudinal waves can propagate, and the formula

determines their velocities dependently on the elasticity module  p  which takes decisive part in such variations of volume" [2, p. 114].

Atsukovsky in his basic work [3, chapter 8] on aethero-dynamics tried to avoid this difficulty by presenting the EM wave as an array of alternating vortexes. He relied on the standard presentation of photon, as follows:

"1. The smallest element of light - photon - carries an energy which, in accordance with the law of Planck, is proportional to the frequency:

2. The light radiated by atom is polarised…

3. Photon as a particle has no electric charge.

4. Photon can have one of two values of spin…

5. Light has a pressure, consequently, photons have their mass.

6. Photons are localised in space, they propagate in vacuum directly and have a constant velocity, like a flow of particles.

7. Light has the properties of interference and diffraction, this allows to think them waves…

All indicated properties of light can be easy explained, if we think photon as a vortex helical structure composed of linear spreading aetherial vortexes located in a staggered order (see Fig. 1)" [3, p. 186- 187].
