Abstract. The frequency dependences
of electromagnetic radiation reflection and transmission coefficients in the
frequency range 0.7…17 GHz of shields based on iron-barium, iron-strontium
and iron-titanium ferrites were studied. The influence of the addition of
powdered electrocorundum to the composition of such shields on the values
of their electromagnetic radiation reflection and transmission coefficients
in the specified frequency range is analyzed.
Keywords: reflection coefficient,
transmission coefficient, ferrite, electrocorundum, electromagnetic shield.
