The influence of the skin effect and active losses in samples of a semiconducting composite with a wide range of conductivity values on the intensity of the EPR absorption line was studied. An approach is proposed that makes it possible to obtain a satisfactory agreement between the calculated and experimental results. It is shown that, depending on the conductivity of the test substance, absorption line intensity, corresponding to a unit volume, can decrease significantly with increasing sample volume.
