Using the method of transforming grid, we study the space and time distribution of scalar potential of dynamic dipole and correlate it with the conventional conception and experimental methods. We analyse the direction diagrams, vector diagrams of electric field strength in the near and far field of dipole, and study the causes, why the wave velocity in the near field of dipole grows. To broaden the area of used method to visualise the fields, we study the field of acoustic dipole and show that its performance fully correlates with the related values of electric dipole.

1. Introduction

In [1] we showed that the scalar potential of dynamic EM field is a time-dependent function and in fact determines all parameters of the force field. On one hand, its spatial distribution determines the wave attenuation. On the other, the vector potential also is fully determined by scalar potential, as it is the consequence of transformation of gradient of scalar potential in dynamic fields. But the vector potential, as is known, determines all dynamic characteristics of the field - in particular, the strength of electric and magnetic fields. So, studying the dynamic scalar potential, we in this way place our study of dynamic characteristics of the field on the sound footing, and there appears an interest to follow, how the dynamic EM field is formed in the view of time-dependent characteristics of scalar potential.

Using the results of modelling of dynamic systems presented in [1], and in particular the pulsing potential source, in this paper we will study the dynamic scalar potential of dipole-like systems.
