Математическая модель оценки электродинамических свойств поля излучения рупорной антенны в ближней зоне

Математическая модель оценки электродинамических свойств поля излучения рупорной антенны в ближней зоне

Abstract

Применение физиотерапевтических технологий с использованием электромагнитных полей с заданными свойствами (плотность потока мощности, направленность, полоса частот, модуляция) предъявляет особые требования к излучающим антеннам. Проведен строгий электродинамический анализ свойств поля излучения рупорной антенны, которая часто используется для экспериментальных исследований взаимодействия биологических объектов с электромагнитными полями. Предложен метод определения параметров возбуждения секториальных антенн для обеспечения баланса энергетических характеристик поля излучения рупорной антенны. Для расчета плотности потока мощности в заданном направлении используются эффективные интерполяционные схемы, обеспечивающие высокую точность и устойчивость численных результатов.

The use of physical therapy techniques using electromagnetic fields with desired properties (power flux density, orientation, bandwidth, modulation) imposes special requirements for radiating antenna. Rigorous electrodynamic analysis of the properties of the radiation field of a horn antenna, which is often used for experimental studies of the interaction of biological objects with electromagnetic fields, is carried out. The method of the parameters determining of the sectorial antennas excitation to provide a balance of the energy characteristics of the radiation field of a horn antenna is suggested. Effective interpolation schemes are used to calculate the power flux density in given direction that provide high accuracy and stability of the numerical results.
