PROCEDURE MEASURING PARAMETERS OF ANTENNAS SUBMERGED IN ABSORBING MEDIUM BY METHOD OF SCALE MODELING, PROCESS OF PREPARATION OF SUBSTANCE TO MODEL ABSORBING MEDIUM AND COMPOSITION FOR PREPARATION OF SUBSTANCE TO MODEL ABSORBING MEDIUM Russian patent published in 2003 - IPC

FIELD: radio engineering. SUBSTANCE: invention refers to technology of antenna measurements, it can be used to carry out laboratory investigations by method of scale modeling of parameters of antennas submerged in semiconducting medium. Procedure includes modeling of structure and relief of medium above and under antenna with subsequent measurement of parameters in echo-free chamber. It is proposed to prepare substance to model absorbing medium from easy-to-obtain and relatively inexpensive materials by way of their thermal treatment and following homogenization ensuring formation of gel maintaining parameters and plasticity in the course of several days. Composition for preparation of substance includes organic filling agent ( coarse flour of hard wheat with high content of gluten ), sodiumcarrying matter, binding matter ( chalk ) and distilled water. Composition does not include any toxic substances, is safe in utilization and can be stored for long time without deterioration of its properties. EFFECT: increased accuracy of measurement of parameters of antennas by method of scale modeling, expanded modeling range of parameters of absorbing media, reduced usage of materials for development of antennas placed in semiconducting media. 5 cl, 4 dwg
