Radiation of a dipole located on axis of s semitransparent disk
Abstract
Asymptotic formulas for scattering fields of arbitrarily oriented magnetic and electric dipoles located on axis of a semitransparent disk were obtained using the Kirchhoff approximation and the stationary phase method. Expressions for the front-to-back ratio of magnetic and electric dipoles oriented parallel to the disk were obtained. Optimization of the disk’s transparency was performed to reduce the back radiation of a magnetic dipole oriented parallel to the disk. Radiation patterns were calculated using the asymptotic formulas and a numerical solution of a singular integral equation.

Излучение диполя, расположенного на оси полупрозрачного диска
С применением метода стационарной фазы в приближении Кирхгофа получены асимптотические формулы для расчета рассеянного поля произвольно ориентированного электрического и магнитного диполя, расположенного на оси полупрозрачного диска. Получены выражения для коэффициента обратного излучения магнитного и электрического диполей, ориентированных параллельно диску. Произведена оптимизация прозрачности диска для уменьшения обратного излучения магнитного диполя, ориентированного параллельно диску. Представлены диаграммы направленности, построенные по асимптотическим формулам, а также полученные методом интегрального уравнения.
