FIELD: medical engineering.
SUBSTANCE: device has two plates manufactured from insulation material bearing metal applicators. Four polygons are arranged on one side of the first plate. Two of them are arranged symmetrically to each other taking one-third of plate surface in its central region. They have saw teeth turned towards each other. Another one-third of the plate has a polygon having one angle turned towards the plate center and two others being directed towards the corresponding plate angles. Polygon having 8 rays occupies the last one-third of the plate surface, two of the rays crossing plate symmetry axis and 6 others resting upon plate edges. Polygons are designed as n-rayed stars where 3<n<8, and at least one of them is directed towards neighboring star ray. Archimedes spiral having 3 coils is arranged on one side of the second plate and one having 2.5 coils on the other side. Both plates are mechanically joined with insulating washer into single unit by means of metal buckles.
EFFECT: increased negative radiation extinction level; uniform frequency response function in high frequency bandwidth.
