Engineering Physics Annotation << Back THE TRANSFORMATION OF AMPLITUDE OF THE SCALAR POTENTIAL FIELD WITH DISPLACEMENT OF THE SPHERICAL COORDINATE SYSTEM I.P. KOZLOV The article develops theoretical research, which was made by E. Ivanov: a) for application of the scalar addition theorem for vector fields, where instead of the scalar potential field superposition principle is necessary to use the principle of superposition of fields; b) to analyze the approximate solutions for small displacement centers homogeneous dielectric spheres that touch without nested within each other – this is a mathematical model of plasma formation; c) to develop consecutive diffraction method when the process is going simultaneously with increasing of size of one of obstruction. Practical directions for use of scalar addition theorem is shown. Keywords: addition theorems, transformation of wave amplitude, local spherical coordinate system, electromagnetic wave, diffraction, two body, cosmos technique, mathematic modeling.
