| الوصف: | Путем усовершенствования непрямого варианта метода граничных элементов заложены основы математического моделирования в безразмерных координатах процесса образования в воздухе хи упроекций относительно электрической напряженности, возбуждаемой прямоугольной магнитной антенной, параллельной поверхности ортотропного композита. ; An article purpose is an application of the improved indirect version of the boundary elements method in dimensionless coordinates to model the becoming process in the air of Cartesian *-projection (*=x,y) of the reduced electrical intensity excited by a rectangular magnetic antenna that is parallel to a plane surface of the orthotropic composite. A magnetic antenna has been modeled by the set of external current point sources those are placed in knots of corresponding above-surface layer of the discretization net. A transition to dimensionless coordinates has been performed separately for electrical intensity Cartesian xand yprojections however adequately for spatial and temporary axises; as well as discretization steps are inversely proportional to the composite conductivity along and crosswise to the reinforcement direction. Therefore Nyquist criterion has been satisfied for Fourier spectral function of the reflection characteristic of the orthotropic composite surface. An analysis of the superposition of spherical waves of point sources has been allowed to find their influence zones covered by boundary elements of suitable horizontal planes in the air. Necessary boundary elements have been considered to calculate electrical intensity E x and E y projections in six possible 2-dimentional sections of its spatial-temporary distribution. A research of the reduced electrical intensity in dimensionless coordinates allows firstly to reveal general peculiarities of its spatial-temporal distribution becoming and secondly to separate the common computational kernel of electrical intensity xand yprojection. Modified Bessel function values are calculated once and besides are tabulated preliminarily ... |
