ELECTROMAGNETIC WAVES; RADIATION; ANTENNA REDUCERS; SEMICONDUCTOR SELECTOR; MIRROR, INTERMEDIATE, BACKGROUND ANTEN The object of research is electromagnetic fields and waves in the near, intermediate and distant observation zones and the characteristics of the orientation of linear lattices of weakly oriented emitters. The purpose of the study is to study the physical laws of electromagnetic wave emission processes by linear lattices of weakly directed vibratory emitters in the near, intermediate and distant zones. Methods of research - theoretical studies, computer analysis, experimental research. The mathematical support is developed - solved the problem and obtained the calculated formulas, developed algorithm and computer programs for calculating electromagnetic fields and waves in the near, intermediate and distant zones of linear lattices of isotropic radiators, a homogeneous aperture antenna with a round aperture, linear lattices of semiconductor resonant vibrating antennas located over an infinite perfectly wired screen. It is shown that the screen magnifies the field gradients and distorts the characteristics of the antenna array direction in the frequency range. The results of further experiments on the investigation of the possibilities of harmonization and rearrangement of the resonant frequency of dipole and loop vibratory antennas by matching elements of various forms in the near-field are presented.
