Abstract
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.
Keywords
sectorial horn antennas, power flux density, equivalent surface currents, the interpolation scheme
